ATN's PVS14 utilizes the same technology as the night vision devices used by military and law enforcement personnel around the world. This compact optic can be used as a simple hand held device, mounted on a helmet for hands free use, or mounted behind a weapon optic. ATN's status as a premier manufacturer grants them access to some of the best Image Intensifier Tube manufacturers on the market – L3 and Elbit. ATN's dedicated team of technicians assemble PVS14 units to the same high standards used by the military using factory-new parts and current production image intensifier tubes. Additional features include IR on and low battery indicators, manual brightness control and auto-shut off function that shuts down the device within seconds when accidentally exposed to bright light, and an integrated IR illuminator for use in extremely low light conditions.
