Binocular Night Vision Device (BNVD) AN/PVS-31A

The AN/PVS-31A BNVD is a compact, lightweight, Gen III dual tube goggle with improved white phosphor tube technology for greater target detection and recognition. Low-light and nighttime maneuvers appear more natural in black and white, with added contrast detail in shapes and shadows providing the operator more visual information for assessment and acquisition. White phosphor offer various shades of intensity between black and white (over black and green), resulting in better contrast and depth perception.

The device has an ergonomic low-profile design and offers superior situational awareness compared to a single tube goggle. Working directly with input from SOF operators, the BNVD was designed to increase system resolution, significantly reduce head-borne weight, improve system center of gravity, provide additional operational utility, and improve overall situational awareness compared to currently fielded dual-tube goggles. The white phosphor BNVD is a follow-on to our legacy, battle-proven AN/PVS-15 and AN/PVS-31 standard green phosphor night vision goggles.
