The ATN NVM-14 is a hand-held, head-mounted, helmet-mounted, or weapon-mounted night vision system that enables walking, driving, weapon firing, short-range surveillance, map reading, vehicle maintenance, and administering first aid in both moonlight and starlight. Each unit allows for vertical adjustment (by using head straps), fore-and-aft adjustment, objective lens focus, and eyepiece focus. The device is also equipped with an infrared light-emitting source. NVM-14 Night Vision monocular utilizes the principle of intensification of the residual light which is reflected from the surrounding objects. The optical system of the monocular consists of: an objective lens, an image intensifier tube and an eyepiece. Even under unsteady brightness conditions, Automatic Brightness Adjustment System always keeps the IIT brightness level constant. The Automatic Protective System controls the existing illumination level through the photo receiver. If the illumination level surpasses 100-300 lx for the following 10 seconds, the monocular will shut off automatically The eyepiece incorporates several LED indicators: - RED – serves as an IR Illuminator Indicator and an Battery Low Indicator at a time. - GREEN – serves as an Excessive Brightness Indicator. If the bright light remains unchanged for over 10 seconds after the indicator turns on, the monocular will automatically shut-off.Couples the EOTECH XPS3 Holographic Sight and the ATN NVM14 to a Picatinny or Weaver rail providing a Day/Night Weapon Sight Solution.
