Product Description

YJN-Ⅱ enhanced night vision telescope

Low-light night vision and infrared thermal imaging equipment constitute a night vision equipment family and they complement each other from the function. Low light night vision equipment can work normally in the night or low light environment, and observe the target that human eye can not see. Its salient feature is the ability to rely on the night sky, starlight and ambient glow lighting to target the image via "passive" way , so that people can observe the target in a dark environment. The infrared thermal imaging system has the ability to penetrate smoke, fog, haze, snow and other restrictions and the ability to identify camouflage, and it can be used around the clock and not be disturbed by the battlefield glare. Uncooled infrared thermal imaging system has reliable performance, and it is easy to operate and maintain. The main technical and tactical indicators have been able to meet the reconnaissance, fire, anti-terrorism and other special tasks need. The infrared thermal imaging equipment is suitable for non-illumination, smoke environment or for hot traces extraction and other tasks; and comparing with  low-light night vision equipment, the poor resolution of, and the image features are not intuitive, so in some cases the use of the two can make up each other to improve the use of performance.

Individuals carrying night vision equipment improve the visibility of the various weather effects, people use night vision equipment to search the important goals, and these equipment can accurately identify the threat target. However, the modern night environment is more and more complex, the battlefield is changing, a single function of night vision equipment has been unable to meet the demands, carrying different types of night vision equipment will increase the burden. Based on this situation, Yuanjin Optical closely tracks the current status and trends of the development of international night vision equipment, developed a combination of low light and infrared thermal imaging function shown together YJN-Ⅱ enhanced night vision telescope.

YJN-Ⅱenhanced night vision telescope adopts the domestic more advanced low-light solid devices, with ultra-high sensitivity, low power consumption, compact structure. Its main feature is the ability to distinguish the details in the low light conditions, and the effect of good observation. At the same time, it adds infrared thermal imaging system. The infrared thermal imaging system use non-refrigerated polysilicon detector components, and has compact structure, low power consumption, high sensitivity, and the main feature is the target detection distance.

YJN-Ⅱenhanced night vision telescope combines the characteristics of low light night vision and infrared thermal imaging technology. The characteristics of the low light part is that the details resolution is strong, and can observe the scene and the details, but the detection distance is not so far. The Infrared thermal imaging is heat sensitive, able to detect the target, the observation distance is farther than the low light system. Because of the penetration ability for rain, snow, fog, smoke and dust , you can find the hidden staff behind the trees. Combining the design of low-light night vision image and the infrared thermal imaging image, the user can simultaneously observes the image of the low light and the infrared thermal imaging through the eyepiece, and maximize the advantages of the two systems, enhance the observation effect, and the ability to detect the target has been greatly improved.
