Product description
PVS31 Type Low Light Night Vision Goggles Binoculars
HNVG-31ND is currently the lightest Helmet Night Vision Binocular. HNVG-31ND uses green or white phosphor coated tubes. It is currently the most widely used low-light-level night vision product in the Air Force pilot series. However, due to its lightweight product attributes and flexible product structure, it has been recognized by many high-end customers in the special field. , The unique design of 40°(±2°) large field of view increases the user's night observation range. It is an excellent choice for workers in special fields to work at night. The product adopts a non-infrared design and only depends on the image intensifier to control the ambient illuminance. The low light is converted into voltage to realize ultra-low illumination imaging. The advantage of this is that the user will not be discovered.
