What is night vision

The ZOJKDB2021 is compact, lightweight and night vision binocular. They utilizetwo high performance image intensifier tubes to provide extremelyclear and crisp images under the darkest conditions. A built-in IRilluminator lets the users easily read a map and function in a totaldarkness environment. lt can be used handheld, head mounted orhelmet mounted for hands-free, or attached to a camera or camcordelfor nighttime photography and law enforcement to document. Thissystem enables walking, driving, short-range surveillance, map readingvehicle maintenance, and administering first aid in both moonlight andstarlight, With automatic protective system controls, the monocular willshut off automatically if the illumination level surpasses 40lux for thefollowing 10seconds. And automatic brightness adjustment systemalways keeps llT brightness level constant.They're easily replaced with3x,5x,óx lens for enhanced range performance.

Function Instruction:

• Automatic shut off when flipped up: The device will turn off automaticallywhen pushing a button on the side of mount and lifting the unit up untilreaches in the top position. Push the same button to lower monocular tothe viewing position, then the device will turn on for continuation ofoperation.

• Mil-spec multi-coated optic: Multi antireflection film can restrain thereflex of lens, which can reduce the loss of light so more light can gothough the lens to get a sharp image.

• Automatic brightness control: When the ambient light changes, thebrightness of the image detected will keep the same to insure a stableviewing effect and also to protect users' eyesight.
