Description
The BNVD-31 Binocular Night Vision Device (BNVD) is a compact, lightweight, dual tube goggle. In a sea of dual tube night vision goggles, the PS-31 is one of the smallest and lightest units by far. The device can be outfitted with various levels of high-performance Gen2+ Autogated White Phosphor image intensifier tubes. Working directly with U.S. Operators input, the PS-31 was designed to increase system resolution, significantly reduce head borne weight, improve system of center of gravity, provide additional operational utility, and improve overall operator situational awareness. These tubes are auto gain-capable, allowing the system to adjust the brightness of their image as situations on the ground dictate. The BNVD has independently pivoting tube housings that allow the operator to run the goggle in a binocular or monocular configuration with Auto-Pod shutoff. Using two tubes at once allows the eyes to create depth perception and increases the ease in maneuvering terrain and obstacles as well as operating devices such as control panels and door knobs. However, monocular configurations allow for ease in transitioning between various lighting conditions that often occur on the battlefield and cause operators to switch between night vision and weapon-mounted optics. Another benefit to the pivoting tube housings is the ability to mount the “flatten” goggle against the front helmet surface when stowed. The ability to pivot the tube housings against the helmet surface creates an overall lower profile, increasing operator safety and equipment life.
