PVS31A Binocular Night Vision Goggles

Weighing in at just under one pound, this system is almost as light as a monocular, yet packs in the same feature set (and then some) of much heavier devices. Working directly with U.S. Special Operations Forces’ input, the AN/PVS-31A was designed to increase system resolution, significantly reduce head borne weight, improves the center of gravity, provide additional operational utility, and improve overall operator situational awareness.

The L3Harris BNVD is one of the lightest binocular night vision systems on the market, with unparalleled optical performance with lightweight optical lens assemblies optimized to maximize the performance of the Unfilmed 2376+ FOM (figure of merit) White Phosphor image intensifier tubes, and features both an onboard AA battery and an external power connector to be used with the supplied external cold weather power supply. The remote pack allows the goggle to weigh in even less and acts as a counterweight to the entire system. It also features built-in dual infrared strobe lights for ground personnel identification. The strobes can be easily activated by a small protected switch under the battery housing. There is no integral infrared illuminator in the AN/PVS-31A BNVD, as this feature was not desired by operators due to its limited use and functionality and added weight/size.

The L3Harris AN/PVS-31A BNVD has independently pivoting tube housings that allow the operator to run the goggle in a binocular or monocular configuration. Using two tubes at once allows the eyes to create depth perception and increases the ease in maneuvering through terrain or obstacles as well as operating devices such as control panels and door knobs. The AN/PVS-31A can be configured to adapt to various situations, giving the user the best of both worlds. Another benefit to the pivoting tube housings is the ability to mount the “flatten” the goggle against the front helmet surface when stowed. Goggles are often worn throughout the duration of a mission, even in daylight hours, because operators may find themselves in a dark environment. NVG’s are often left in the stowed position until needed so they can be instantly accessed. But, this causes a snag hazard since the goggles can easily bang into objects while flipped up. The ability to pivot the tube housings against the helmet surface creates an overall lower profile, increasing operator safety and equipment life.
