Information and Knowledge about Military Binoculars

The optical systems of military binoculars are different. Most military binoculars have reticles, and their reticles used at night are also illuminated. The exit pupil of military binoculars is relatively large, so that observers can wear gas masks. In order to prevent hitting the head when shooting, some scopes have an exit pupil distance as large as 70 or 80 millimeters, and an eye mask and forehead guards with moderate hardness are also provided.

In terms of optical performance and structural performance, military binoculars are more excellent and reliable, because they are more carefully designed, with superior materials and sophisticated craftsmanship, such as good image quality, less stray light, and matching magnification to the size of the entrance pupil Achieve the best resolution.

Due to the high quality requirements, military binoculars must undergo environmental tests before they leave the factory, which generally include vibration tests, high temperature (ten 55°C) tests, low temperature (45°C) tests, rain or water immersion tests, and air tightness tests. After these tests, the product performance can still be guaranteed within the specified range before leaving the factory. Some products also come with a dryer inside the lens body. The air is taken out before leaving the factory and then filled with dry air or nitrogen, which can effectively prevent the internal lenses from growing moldy and fogging in the future. Ordinary civilian telescopes generally do not do environmental tests, or only do partial tests. This is difficult for people to understand from the market, nor can it be seen from the appearance of the product.


Main structure

Mirror body group

Mirror body group: The mirror body group is the main body of the telescope, divided into left and right mirror bodies, connected together by a connecting shaft, and its function is to support the upper and lower right-angle prisms and connect the objective lens group and the eyepiece group.

Objective lens group

Objective lens group: The objective lens group is composed of lens, objective lens barrel, etc. The objective lens group and the lens body are connected together with threads, and its function is to receive light from distant objects (or targets) and image them on the focal plane.

Eyepiece group

Eyepiece group: The eyepiece group is composed of lens, eyepiece frame, diopter handwheel, etc. The eyepiece group and the lens body are connected together with a threaded pressing ring, and its function is to magnify the image formed by the objective lens for human eyes to observe. Turn the diopter handwheel to adjust the diopter of the program mirror to meet the use of human eyes with different diopters Requirements, the range is ± 4 diopters.

Connecting shaft

Connecting shaft: The connecting shaft is the connecting piece of the left and right mirror bodies of the telescope. It is also the hub to realize the adjustment of the eye distance in the range of 58-74mm, and it is also the core of the binocular image.

Cover and strap

Protective cover and strap: The objective lens cover and eyepiece protective cover are designed to protect the objective lens and eyepiece lens. Cover the telescope when not in use to protect the lens from damage. The strap is connected to the left and right mirrors of the telescope, and the strap can be hung on the neck of the user when in use to prevent damage to the telescope due to loss of hands.


Instructions

To use a telescope/binoculars, you must first set the diopter. Holding a binoculars/telescope to observe a distant target kilometers away. Set the left and right eyes separately, turn the eyepiece diopter until it is clear, and remember the number of divisions of the diopter. Then set the eye distance. The eyes are observed through the telescope, and the binoculars/telescope tube is moved to make the two fields of view merge into a circle. At this time, the number of divisions of the eye distance is the eye distance of the observer. After using the binoculars/telescope for the first time, you should remember your sight and eye distance, and then you can set it directly when you use it. When using a telescope to observe, you should hold it with both hands and clamp your elbows close to your chest. This posture is relatively stable. If there are fortifications or other supporting objects, the elbows should be supported as much as possible, especially when using a large-magnification telescope. When using the telescope in snowy fog or under strong sunlight, you can wear a filter to make the observation clearer.

The density division in military binoculars/telescopes can use the formula of "upper interval, lower 1000, density and distance on both sides of the pendulum, if you want to find that number, multiply the diagonal to divide the adjacent side" formula, you can measure the direction angle, the height and the angle The distance to the target. This is specifically described in "Military Topography" and is a required course for every officer or scout. 

Eye distance adjustment

First, adjust the positive and negative diopter scales of the left and right eyepieces of the binoculars/telescope to 0 scale. Hold the left and right mirror bodies of the telescope with both hands, and search for distant targets while stretching or pressing the left and right mirror bodies so that the eye distance of the telescope is the same as the pupil distance of the human eye (the full field of view seen by the human eye is a circle形), stop the adjustment.

Object image adjustment

First search for the target. After locking the target, turn the left eyepiece dioptric handwheel to make the target image and reticulated image of the left side of the telescope completely clear, then turn the right eyepiece dioptric handwheel to make the right side system target image completely clear. This completes the adjustment of the observed target. Because the optical path of the telescope is designed with dynamic auto-focusing function, after the clarity of the telescope is adjusted, there is no need to refocus when observing targets at different distances again.

Night use

When the ambient light is dim or when observing at night, it is recommended to use a telescope with an exit pupil diameter of 7mm or more. Because the pupil diameter of the human eye is about 2-3mm in the daytime and about 6-7mm in the dark, the telescope can collect more light than the naked eye.


China military use

China's military optical industry began in the mid-1930s. After more than 70 years of unremitting efforts, it has developed from the initial acceptance and repair to the completely independent research and development in the 21st century. Domestic military binoculars have always been the mainstream collection of domestic military fans. According to the order of production, there are about the following types of common domestic military binoculars.

Chinese official 6×30 telescope

The Zhongding Telescope is the first military binoculars designed and produced by China. It was born in April 1939, the most difficult period of the Anti-Japanese War. It was designed and developed by Gong Zutong and Jin Guanglu, the founders of Chinese Optics. According to the production time and the logo of the mirror body, the Chinese version telescope can be divided into two types: Kunming 22 and the middle version.

Kunming Twenty-two is also known as Kunming Mirror. It was named Jingzhishi in the early days. The mirror body was painted in black. It was produced by the 22 factory from 1939 to 1941. The mirror adopts the rectangular frame logo popular in Europe at that time. The left shoulder frame is superscripted with "Double Wang" and the subscript "6×30" is superscripted. The right shoulder frame is superscripted with "Kunming" and the subscript is "Twenty-two". The number is engraved under the shaft.

The middle form was produced in 1942 after the 22 factory and the 51 factory merged into the 53 factory. The mirror body was painted with green paint, and the left shoulder prism was covered with an oval logo frame. The seal script "medium formal" was marked on the frame, and the seal script "53" was subscripted. "", with the words "Ordnance Department" in the seal script below the logo frame, an oval-shaped ranging logo is engraved on the right shoulder, and the number is stamped under the central axis.

Although the two telescopes have different logos, the structure is exactly the same. A total of 23,507 were produced, of which 1,866 were produced by 22 factories from 1939 to 1941, and 4,429 were produced from 1950 to 1954 after liberation. The rest were produced by 53 The factory is producing in the formal. The Chinese telescope is the starting point of China's optical industry, and its comprehensive performance has basically reached the international level at that time. Under extremely difficult conditions, it is very difficult for China with a weak industrial base to develop and produce telescopes of this level on its own. It is worth mentioning that during the Civil War, the 53 factory also produced the official monocular telescopes. The monoculars had fine-grained formal skins and no reticles. Only 430 were produced, which is a rare and precious collection.


Type 62 8×30 binoculars

The 62-type binoculars is the first military binoculars produced in mass production in China after the founding of the People's Republic of my country. It is produced by many domestic manufacturers, but the largest output is the 298 factory, which is still produced in small batches. The mirror is imitated in accordance with Soviet technology. Except for the lack of a red button, its shape is very similar to the Б8 red button, and a drying chamber has been added according to the actual domestic environmental impact to improve moisture resistance. The performance of Type 62 is similar to that of the Б8 binoculars, but the binoculars produced by the 298 factory has a heavier degree of yellowish observation. It is generally believed that the type 62 with the box "jiang" has the best optical performance. Like the B8 telescope, the Type 62 was also produced in the infrared type, which was used by the North Vietnamese army during the Vietnam War. As mainstream equipment, the Type 62 telescope will be gradually replaced by the more advanced Type 95 after more than 40 years of service. However, due to the amazing production and inventory of the Type 62, it is estimated that the Type 62 telescope will continue to exist for a long time. In the equipment sequence of our army. Type 62 produced by the 298 factory can be roughly divided into three types: early type, mid-term type, and late-stage type according to the logo of the mirror body. The early type is marked with "62 type", the medium type is marked with "62 type", and the late type is marked with "62-". "8WYJ", it is said that the optical performance of the late model has been improved, and its iconic serious yellowish defect has also been improved.

Type 74 7×50 telescope/binoculars

After the Sino-Soviet ties, our country lost the channel to import telescopes from the Soviet Union and Eastern Europe. In order to meet the needs of the troops, our country designed 74 telescopes based on Zeiss 7×50 telescopes. The performance of the Type 74 telescope is roughly equivalent to that of the Zeiss 7×50. It is mainly equipped with naval forces. There are also Baoding and Changguang telescopes designed with reference to Zeiss 7×50, but since the latter two are basically not official military telescopes, I will not repeat them here.

Type 88 12×42 telescope/binoculars

The 88-type telescope is the only American-style prism-structured telescope equipped by our army, and it is also the first highly-sealed telescope, mainly equipped with armed police forces.

Type 95 7×40 telescope/binoculars

As a new equipment that has just been installed, the shape refers to the length of the Zeiss telescope in West Germany. It has the advantages of excellent optical performance, moderate size, reasonable specifications, and strong environmental adaptability, especially the excellent mirror The optical performance makes everyone who has used it feel unforgettable. Because it is new equipment, military fans have collected civilian high-sealing or military-to-civilian versions. The performance of the military version 95 that is really equipped with troops is still a mystery, but it is certain that the performance of the military version 95 is definitely not. Lower than the civilian version. It is said that the military version of Type 95 has anti-laser function. If this is the case, it means that Type 95 has successfully solved the contradiction between optical performance and anti-laser design, because the essence of anti-laser design is to block specific wavelengths of light from passing through. The principle that telescopes should increase the light transmission rate as much as possible is contrary to the principle. Therefore, telescopes with anti-laser function generally sacrifice the optical performance of the optical part. The most representative ones are the M22B and M22G telescopes equipped by the US military. The degree of color cast is very serious, almost To the point where it affects normal observation.


T98 type 7×50 telescope/binoculars

Compared with the 95-type that frequently appeared on the scene, the situation of the T98-type is awkward. When a large number of troops changed into the Type 95, the T98 type only got a symbolic order. When the Type 95 frequently appeared on the military exercise field, the T98 only appeared in the VIP viewing seats once. But this does not mean that the T98 type is not an excellent military telescope. It can only be said that it is untimely. Although the optical performance of the T98 type is slightly inferior to that of the 95 type, its modular design is unique in China. If it was born a few years earlier, I believe it will definitely occupy an important place in our army’s optical equipment.


History development

Early military telescopes/binoculars were of Galileo structure. Although this type of telescope has a simple structure and high light transmittance, its multiples and observation field of view are very small. At the end of the 19th century and the beginning of the 20th century, military telescopes have successfully solved the problems of multiples and field of view with the pro-prism structure. From the beginning of World War I to the end of World War II, military telescopes in this period are convenient to carry 6×24, 6×30, 8× 30 is the main, which has a lot to do with infantry fighting mainly on foot. The navy and armored forces are mainly equipped with 7×50 and 10×50 telescopes with good observation stability but larger size and weight. Military telescopes in this period all used metal as the mirror material. In the early days, brass was used more often, and aluminum alloys were used more in the later period. At that time, people believed that there was no need to use expensive coating processing technology on military telescopes, so this period Most of the telescopes are not coated.

In the Cold War and post-Cold War era, the use environment of military telescopes has undergone tremendous changes, and the design ideas of telescopes have also undergone major changes. The first is the realization of mechanization. Users often use telescopes on the bumper, which has higher requirements for the observation stability of the telescope, so the 7×40 and 7×50 specification telescopes have become the mainstream. Secondly, the shadow of nuclear, biological and chemical warfare makes people have to consider the use of gas masks when designing telescopes, so more and more eyepiece covers that can be folded (lifted) appear in military telescopes, and this design is also rapidly Used by civilian telescopes to facilitate users who wear glasses. The extensive use of new technologies such as coating technology, image stabilization technology, lens encapsulation, non-metallic materials, and laser protection have also greatly improved the performance of military telescopes. After entering the information age, all kinds of advanced detection equipment have weakened the role of telescopes to a certain extent, and military telescopes have not seen any qualitative leap and change, but in the foreseeable future, military telescopes will still be used as a close observation instrument Will continue to play an important role.

The military mirror is used to observe the battlefield, study the terrain and objects and reconnaissance targets. It can also be used for simple measurement with the dense division in the right eyepiece. The magnification of telescopes is generally divided into three levels: medium magnification (6-10 times), large magnification (10-20 times) and variable magnification (German 20-40 times, domestic 25-40 times). Military telescopes used to be 6 times and 8 times the majority. Now 7 times military telescopes are quite popular (the reason is that the human visual distance is about 7km). In addition to the United States and Germany, Russia and China have successively developed 7-fold military telescopes and equipped troops. The larger the magnification of the telescope is not the better. If the magnification exceeds 10 times, it should usually be mounted on a tripod. If it is only used with an arm, the tremor of the hand will have a serious impact on the observation and the observation effect will be worse. In addition, when evaluating the selection of telescopes, the geometrical optical power should also be considered. Generally, a small optical power telescope (exit pupil diameter of 2-3mm) is suitable for use under good lighting conditions; medium optical power (exit pupil diameter of 3-4mm) is suitable for use under general lighting conditions, such as our Army Type 62 8 times observation infrared telescope (exit pupil diameter is 3.7mm); high light power (exit pupil diameter is 4-6mm) is not only suitable for daytime use, but also suitable for use under low illumination conditions at dawn and dusk, such as our new Y/GG95 -7 telescope (exit pupil diameter is 5.71mm). For medium magnification (6-10 times) telescopes to achieve military-level visual effects, the light transmission rate should be considered. 7 times with an objective lens size of 40mm, 8 times with an objective lens size of 50mm, and 10 times with an objective lens size of 60mm, can achieve very good results. Stability and best imaging comfort.


China's development

The first telescope to flow into our country was brought into Beijing by the German missionary Tang Ruowang in the 6th year of Ming Qi (1626). Tang Ruowang and Li Zubai jointly translated the book "Distant Mirror Theory", introducing the manufacturing method of Western telescopes to China. In the 2nd year of Chongzhen (1629), the academician Xu Guangqi asked to assemble three telescopes to measure the astronomical phenomena. The telescope supervised by Tang Ruowang was also visited by Emperor Chongzhen. Chinese people independently made telescopes earlier, and it is recorded that Sun Yunqiu, a native of Suzhou in the late Ming Dynasty. According to Kangxi’s "Wuxian Chronicles", I climbed to Huqiu and used Sun Yunqiu’s self-made "Thousand Miles" to try it out. See you later.” Bo Jue, a Suzhou native in the late Ming Dynasty, was the first to use telescopes in China. "Bo Jue creatively placed the telescope on a self-made artillery to improve shooting accuracy.

In the Qing Dynasty, especially after the Opium War, foreign telescopes gradually entered China. For example, on the portrait of the concubine Xiangfei painted by the court painter Castiglione Castiglione during the Kangqian period of the Qing Dynasty, the concubine Xiangfei with a helmet and armor is eye-catching holding a single-scope. From the illustrations in the book "Following Lord Elgin’s Mission to China and Japan" by the British Russian Li Fan in 1859, it can be seen that the British and French coalition forces that invaded Guangzhou at that time used monocular Galilean telescopes (see color picture, France) Type 16 10 times telescope).

In May 1937, the Military Optical Equipment Factory of the Military and Industrial Administration of the Kuomintang Department of Military and Political Affairs, according to Dutch drawings and materials, imitated a sample of the Dutch-style 3x straight telescope within 3 months. In the same year, Gong Zutong, a publicly funded foreign student from the University of Berlin, was ordered to do an internship at the Hensholz factory in Germany. Under the guidance of Professor Widt, he and Jin Guanglu designed a 6×30 (ie, 6 times magnification, objective lens diameter 30mm) binocular military telescope. In January 1939, Kunming 22 Armory (later merged with 51 Armory and changed to 53 Armory) began trial production of binoculars. Three months later, China’s first binocular military binoculars were trial-assembled. From 1939 to 1949, more than 20,000 were produced. This type of telescope was once named "Jingzhi" by He Yingqin, the then Minister of Military and Political Affairs, and was later renamed "Chinese Form". The left and right eyepieces of this type of telescope can be adjusted as needed. The right eyepiece has dense divisions for measurement. The lens body is decorated with a heat-proof layer made of vulcanized leather. The pattern is large and the appearance is rough. The elliptical markings of "Medium Formal" and "Made by the Ministry of Military and Political Affairs" are embedded in the end face of the mirror body with extremely thin metal wires.

Before the War of Resistance Against Japan, the Kuomintang army not only used Germany in tactical thinking, but even its weapons and equipment were imported or made in Germany. The telescope is no exception. The famous "Zeiss" telescope is more imported from Germany. In the middle and late stages of the Anti-Japanese War, the main force of the Kuomintang army was equipped with m3 type 6×30 and m16 type 7×50 military telescopes produced by Westinghausen provided by the United States in batches. These two types of telescopes were heavily equipped with Allied forces during World War II. It is worth mentioning that after the war, the Japanese Self-Defense Forces and the Taiwan Army also imitated American telescopes. American telescopes are different from European telescopes. They can only be opened from the back (eyepiece) direction. This structure is reliable and has good sealing performance, but it is complicated to manufacture. ,high cost.

Whether it is the "Chinese official" of the Kuomintang army or the military show binoculars imported from Germany, the United States, Britain and Canada in different periods, they have all been seized by the People's Liberation Army in large numbers and have become trophies for my use. For example, the Red Army had a German eight-fold Zeiss seized during the anti-encirclement and suppression campaign in the Central Soviet Area. It was always used by Zhou Enlai during the Anti-Japanese War; when Marshal Peng Dehuai commanded the Northwest Liberation War, he had always used a German six-fold Zeiss. Zeiss". During the War of Liberation, there were many American telescopes in the Northeast Field Army. For example, Marshal Luo Ronghuan used the m3 6x telescope; the Lieutenant General Hu Qicai, who was famous for the Tashan blockade, used the M167x telescope. During the Anti-Japanese War, I The army seized a variety of 6-fold military telescopes for the Japanese invaders. Among them, the Japanese telescope marked "Fuji" was actually a copy of the German "Zeiss". Our Eighth Route Army-the first draw of the five questions, was captured by the Japanese Army according to the equipment of the 21st Brigade of the Itagaki Division. Of this type of telescope. The Japanese army also has the so-called "Cannon II" 6-fold telescope for artillery, as well as toko 8-fold and 10-fold telescopes.

In the early days of the founding of New China, most of the telescopes equipped by the People’s Liberation Army were imported from the Soviet Union, the Czech Republic and the GDR, such as the б-6 (6×30) and б-8 (8×30) telescopes imported from the Soviet Union in the 1950s, and the Czech хък 6 ×30, 30хък 8×30 telescope, and "Zeiss" 6×30, 8×30 and 7×50, 10×50, 15×50 telescopes manufactured by Jena, the Democratic Republic of Germany, imported from China in the 1950s For military binoculars, whether it is optical system or appearance, the German "Zeiss" is the best, followed by the Soviet Union. The Czech хък telescope has a rough appearance, and the mirror body does not use a heat-proof layer of vulcanized rubber, but only painted with black paint.

In the early 1960s, my country's telescopes, like other weapons and equipment, took the road of self-designed and produced. my country produced 62-type 15×50 telescopes on its own. The difference between these three domestic military telescopes is that the front cover of the prism chamber is equipped with a fixed dryer, especially the left objective lens of the 62-type 8x observation telescope is equipped with a photosensitive screen, and the infrared light source can be seen through the eyepiece. You can observe the enemy’s use of infrared night vision equipment. In recent years, my country has adopted advanced technology to design and produce GG88-212 12 times and Y/GG95-7 7 times telescopes for the army. In addition to good sealing performance and strong light power, these two telescopes also add a line-of-sight curve in the measurement division, which can quickly read the approximate distance of the target.

The development of military binoculars in my country is relatively late. Although the official 6x30 military binoculars were also developed before liberation, due to the limitation of level and variety, they are mainly imported from Germany, the United States and other countries, mainly 6x30 and 7x50. In the early days of the founding of the People’s Republic of China, there was no mass production capacity for military telescopes, so it imported a large number of military telescopes from the Democratic Germany, the Soviet Union, and the Czech Republic, which had the leading optical technology in the socialist countries at that time. that. Zeiss 6x30, 8x30 and the Soviet Union's б6 (6x30), б8 (8x30) several medium magnification types are mainly, in addition to a small amount of Jena. Zeiss 7x50, 10x50, 15x50 large-caliber models. These binoculars all represent the advanced level of the world at that time. Some of them can still be used today, but most of them are not well-kept and frequently used, and the lens coating has been wiped and mildewed. The use value is not high. However, the use value is not high. The quantity is very small, coupled with the famous background, so the collection value is very high, a Jena. The general transaction price of Zeiss 6x30 and 8x30 models is also 700 or 800 yuan, and the 50mm caliber is even more than 1,000 yuan.


Zeiss 6x30 military telescope

The general transaction price of Zeiss 6x30 and 8x30 models is also 700 or 800 yuan, and the 50mm caliber is even more than 1,000 yuan. After hard work, our country finalized the production of Type 62 8x30, 8x30 Red Type, Type 63 15x50 military telescopes in the 1960s. These three types of telescopes were all manufactured in accordance with the same telescope structure and style of the People's Republic of China and the Soviet Union at that time. Large field of view, optical performance and robustness have reached a very high level, and it is still the main equipment of the Chinese military. It should be noted that these three types of telescopes all refer to Minde’s 15x50 drying chamber and also designed this component. Although this component is of little practical value, it does demonstrate the spirit of my country’s optical industry at that time. The 62-type 8x30 viewing red type is designed on the basis of the 62-type 8x30 based on the Soviet Union’s 8x30 viewing red type. It mainly adds a photosensitive screen, which can detect whether the other party uses an infrared night vision device. Its output is small, mainly for scouts. This viewing function is outdated today, but its collection value is extremely high. In addition, most military telescopes in our country do not have lens caps. The 62-type telescope is rarely used by the people. At the same time, because it can be used in most cases and has good optical performance, it is good for both use and collection. The general transaction price of the product is around 500-700 yuan. The author believes that the 62-type 8x30 telescope is the most successful telescope developed in our country in terms of both shirt quality and overall optical performance.

Zeiss 8x30 military telescope

At that time, our country also equipped a very small number of large binoculars for the border observation post, mainly Jena of Minde. Zeiss 25-40x80, 20-31-50x80, and later my country also produced several large-scale binoculars imitating them, of which the 25-40x100 from the 98 factory is the best. The most important thing in buying second-hand military binoculars is that the lenses and other optical components should be as good as possible. If you want to use them, it depends on whether the optical components are moldy, the severity of mold growth, and whether the image is doubled. As for the appearance, due to the earlier age, the fineness is mostly older. my country developed several military telescopes later, but due to various reasons, there was no formation. The latest military binoculars developed in my country are the 95-style 7-fold series, and still have a full-metal structure of cadmium sulfide leather. The appearance and workmanship have been greatly improved, and new optical materials have been used. With mc coating, after trial, its brightness and color reproduction are very good, and the imaging sharpness is high. Compared with the phenomenon of severe yellowish imaging of my country's military telescopes, it has been greatly improved, but the observation field is not as large as 62, only equivalent to medium Up the level. The biggest improvement of the Type 95 telescope is the use of high-sealing technology, which has good dustproof and waterproof performance, and it is equipped with a very beautiful leather backpack. The 95-type telescope adopts a new ranging curve for the first time in the ranging method, which can directly read the distance. According to the research department, all aspects have reached the international advanced level. The Type 95 telescope has several specifications such as 7x40 conventional type, 7x40 ranging type, 7x40 camouflage type, and 7x50 conventional type and 7x50 ranging type developed for a certain country.

Type 95 camouflage military telescope

The Type 95 telescope has now begun to equip our troops, but its price is relatively high (it is reported that the transfer price is 1780/yuan). Due to my country's strict restrictions on the outflow of military products, and various other reasons, domestic military binoculars are extremely difficult to see in the private market, and the price is relatively high.


Multifunctional digital

Multifunctional digital military binoculars can be said to be an indispensable equipment for modern digital battlefields.

Domestic "Victor" multifunctional digital telescope

The "vector" (vector) series of multifunctional digital telescopes integrate the four functions of telescope, distance measurement, north and angle measurement. The measured distance and angle data are directly transmitted to the terminal or computer in digital form. It has dozens of functions and has a wide range of uses. It is an essential equipment on the digital battlefield.

The "Victor" series telescopes were put on the market in 1994 and equipped with troops. They consist of a laser rangefinder, a digital magnetic compass, an inclinometer, and optical and electronic components. It is a multifunctional integrated telescope. It adopts high-tech design and is a sophisticated intelligent observation and target reconnaissance system, which is convenient for conventional troops and special forces to perform various tasks, such as battlefield surveillance, orientation, ranging and angle measurement. This type of telescope can be hand-held or placed on a tripod. It can give troops the magical effect of first hit on the digital battlefield.

With the development of science and technology, various services and arms require observation equipment of good quality, high precision, advanced technology, sturdiness and durability, which can withstand the severe tests of current and future global military operations. The "Victor" telescope is a scientific research achievement at the forefront of electronic optics technology and is a new generation of high-performance observation equipment. The optical system can provide bright and clear images. The coated lens can prevent the 1.064 micron laser radiation emitted by the enemy's laser equipment and protect the eyes of the operator. The laser rangefinder uses a first-class diode laser that is absolutely safe for the human eye. The digital magnetic compass with inclinometer has high accuracy in direction and angle measurement.

"Victor" telescope is simple to operate and easy to use. Right-click, you can measure a target from 5 meters to 12 kilometers. The laser rangefinders of the "Victor" IV and "Victor" 21 telescopes use 1.55 micron potassium arsenide laser diodes, whose laser beams cannot be detected by laser alarm devices and low-light night vision devices. "Victor" 1500 telescope is the best observation equipment used by snipers. It can accurately determine the target distance of more than 2000 meters (the maximum range of a sniper rifle is 2000 meters), which can avoid the sniper's visual error of the target distance and achieve the first hit effect.

The "Victor" series of telescopes are rugged, durable and highly reliable, and can withstand the severe test of long-term reconnaissance missions in snow-covered mountains or hot desert environments. In addition, the "Victor" telescope is also suitable for amphibious combat troops to conduct water target reconnaissance. The telescope is waterproof to a depth of 1 meter, and it is still waterproof at 1 atmosphere of water. The telescope adopts a die-cast aluminum shell and a durable shock-absorbing rubber sleeve, which is more suitable for use in an amphibious environment. If you accidentally fall into the water, don't worry, it will float.

At present, the "Victor" series telescopes have been widely used in special forces, marines, border troops, infantry, artillery, sniper units, and engineering construction.


American "Doctor Can" Tactical Telescope

The U.S. Bushnell tactical telescope is a new military telescope designed for the tactical characteristics of the U.S. Navy. Due to the special XTR technology used in the mirror, its detection effect in low-light environments is better than infrared telescopes. Compared with the high-power telescope, the high-brightness technology has a clearer image. Although it is only 7 times, it has made a great breakthrough in wide field of view and visual stabilization technology. It is a true night vision telescope with high technical content.
