The ATN NVM14-4 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 Night Vision Device is also equipped with an Infrared light-emitting source.
The ATN NVM14-4 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.
