ATN NVGOPS3143HFW | PS31 BNVD-51 1x 18mm Gen 3 Night Vision

The ATN PS-31 BNVD-51 (NVGOPS3143HFW) is a binocular night vision system engineered to accept U.S.-made Generation 3 image intensifier tubes with auto-gating and white-phosphor output. It provides 1x magnification through an 18mm objective and is built to reduce head-borne weight while improving balance and situational awareness. The dual, independently pivoting tube housings permit either binocular operation for depth perception or monocular operation for easier transitions between night and daylight environments. The system ships with basic accessories for helmet mounting and field use.

Common applications include night navigation and search & rescue operations, as well as wildlife observation where extended low-light performance and low weight are priorities.
