Night Vision Scope NVB22/NVB32
NVB22 is a low light night vision binocular. They utilize two high performance image intensifier tubes to provide extremely clear and crisp images under the darkest conditions. A built-in IR illuminator lets the users easily read a map and function in a total darkness environment. It can be used handheld, head mounted or helmet mounted for hands-free, or attached to a camera or camcorder for nighttime photography and law enforcement to document. This system enables walking, driving, short-range surveillance, map reading, vehicle maintenance, and administering first aid in both moonlight and starlight. With automatic protective system controls, the monocular will shut off automatically if the illumination level surpasses 40lux for the following 10seconds. And automatic brightness adjustment system always keeps IIT brightness level constant.
