This product is night vision classic, has a very high reputation in the world. Using the 1 generation + image intensifier tube, it has a further observation distance and clearer observation effect than the same level product.

has 5 times magnification, 50 mm diameter, its excellent optical system and imaging bright generation with high performance image tube will bring you a clear and sharp effect.

Anti glare function and has safety, ensure that equipment is not by accident, irreparable damage. This is greatly different from the usual encounter with strong light damage to the night vision device, so that your use of comfort.

using advanced ISE image sharpness enhancement technology, generate clear vision, to observe the details more abundant. Widely used in security surveillance, night hiking, boating, photo viewing, etc..

- uses the equipment and the basic parameters of

- strong and lightweight iron structure can protect the internal components, and provide users with comfortable touch, suitable for all types of use. But it has distant observation ability and long battery life, night vision makes this easy to use and can be widely used in entertainment and professional applications, including security, hunting, boating, entertainment, astronomy, natural observation and camping.

- how to adjust this product definition

- focusing sequence: first adjust the eyepiece, and then adjust the lens can be adjusted several times until the clearest

- after completion of the adjustment, no matter how the distance change, do not have to adjust the eyepiece observation, according to the different distance of the target, adjust the focus to the most clear lens can be

- night vision to see how far

- night vision instrument is night target identification equipment, can not see the specific details, to identify how far the target, is directly related to the size and environmental targets, such as mountain, can be said to more than 1000 meters, if the man is 50-100 meters, the specific effects can reference renderings the shooting.

The working principle of - night vision is what? Why can not distinguish color?

, eyes of ordinary people can not feel so dark when there is no infrared, light person can not see things, and any objects above absolute zero temperature in outward infrared radiation, including your body. Infrared detection devices can feel the infrared, the analog signal through to background noise, amplification, filtering and other image processing methods, the reduction of the outline of the object to be detected is the basic principle of infrared night vision instrument

, but the color is very difficult to restore, so the image to see the infrared night vision instrument rarely is the color of the .

- is also a night vision, what is the difference between our products?

- night vision instrument according to the enhanced tube grade for generation, two generation and three generation .

- third generation is the most sophisticated civilian level night vision technology. The surface is coated with a layer of very sensitive gallium arsenide photocathode coating, which can convert light into electrical energy in a very weak light. The third generation provides clear, sharp night vision images. A high performance image intensifier tube, a minimum of 51 lp/mm resolution, 3 units higher than the minimum standard of 45 lp/mm. Line / mm (lp/mm) is a unit used to measure the high resolution image intensifier produces image clarity.

The development of - pathway disc of the second generation, can produce tens of thousands of electron number. This produces a clear map like, at night under the condition of zero, and a generation of generation compared to not easy distortion.

- the first generation of the materials used and the zero generation compared to more efficient conversion of photoelectron. These devices are capable of operating at a lower light intensity than the zero generation, known as "star brightness". Night vision instrument imported usually use the first generation image intensifier, even if they claim to the second generation, actually still belongs to the first generation category.

our products for the generation of image intensifier tube, compared with the zero generation more efficient conversion of photoelectron, so the ability to work effectively in lower light intensity. At the same time, compared to the two and the three generation of expensive prices (basically thousands of dollars), as a civilian equipment, but also high quality and low cost products.
