What is the main difference between the third-generation and second-generation night vision devices?

The third-generation low-light-level night vision device uses a highly sensitive gallium arsenide photocathode thin-film tube. Compared with the second generation, the sensitivity has increased by 4-8 times, and it can image in weaker light, and has a stronger ability to detect targets in the dark night.

What is the difference between low-light-level night vision and infrared night vision?

Infrared night vision does not rely on external light, can work normally in a completely dark environment, and can clearly present the temperature difference between the target and the surrounding environment. Even if the target is hidden in the grass, woods or caves, as long as there is a difference between its body temperature and the background, it can be easily found.

How to use low-light night vision goggles correctly?

Before use, carefully check whether the appearance of the low-light night vision goggles is damaged, such as whether the lens has scratches or cracks, whether the body has bumps, etc. At the same time, check whether the various adjustment buttons and knobs can work properly.

How does HD CMOS visible light perform in low-light environments?

In extremely low-light conditions, some HD CMOS cameras can be used in conjunction with infrared sensors to capture infrared light information and fuse it with visible light information, further enhancing night vision capabilities and adapting to more complex and changeable nighttime environments.

Advantages of HD CMOS visible light lens

HD CMOS has good photosensitivity under low light conditions, can capture more light, so that relatively clear images can be taken in dim environments, reducing the need for additional lighting equipment, and is suitable for scenes such as night monitoring and astronomical observation.1.

Differences between civilian and military night vision goggles in actual use

Civilian night vision goggles are mainly used for non-combat related activities, such as outdoor adventures, to help explorers observe wild animals, find paths, identify terrain, etc. at night. Military night vision goggles are used in military operations and national defense security related scenes, including battlefield reconnaissance, allowing soldiers to observe the deployment, equipment, personnel mobilization, etc. of enemy forces at night.
