The PVS-14 Night Vision Monocular is the standard-issue U.S. Military night vision optic and is used by special ops units throughout the world. These units boast the highest quality in optics, design, and functionality. Their versatility makes them the premier choice for law enforcement and military professionals. PVS-14 units can be mounted on a helmet for hands-free use, behind weapon optics, or simply used as handheld devices. The PVS-14 provides night vision assistance to one of the operators eyes, leaving the other to retain its natural night vision. This is important when operating in changing light conditions in the field, allowing users to switch between aided and unaided vision seamlessly. Military and law enforcement operators require the ability to instantly switch between dynamic light conditions as the situation develops. The PVS-14 can be assembled with various levels of Image Intensifier tubes. ATN, being a premier manufacturer, has access to the best High-Performance tubes from leading U.S. Image Intensifier Manufacturers on the Market, such as L3 and Elbit. Our professionally trained and experienced technicians assemble the PVS-14 according to Mil-Spec Standards, using factory-new parts and current production image intensifier tubes. Additional features include IR on and low battery indicators, manual brightness control, an auto-shut-off function that deactivates the device within seconds when accidentally exposed to bright light, and an integrated IR illuminator for use in extremely low light conditions.
