The PVS‑31 is the pinnacle of binocular night vision technology, offering unmatched depth perception and situational awareness through its dual‑tube design. The 40° field of view per eye provides a wide, panoramic view, while the 1× magnification gives a natural, life‑size image with unlimited depth of field. The optical system incorporates 25mm F/1.2 lenses with multilayer broadband coatings, ensuring maximum light transmission and minimal glare. The manual focus facility allows adjustment from 250 mm to infinity, enabling both close‑up inspection and long‑distance observation. The diopter adjustment (-4 to +4) and continuous interpupillary adjustment (52‑72 mm) with manual locking ensure comfortable viewing for any user. The PVS‑31 features an advanced auto‑gated power supply (optional) that automatically adjusts tube gain to match ambient light, protecting the tubes and extending service life. The bright‑source protection and low‑voltage alarm safeguard the unit in the field. The integrated 850 nm IR illuminator (20 mW) provides auxiliary illumination in total darkness. The ergonomic control dial offers OFF/ON/IR/AUTO modes, while the rollover detection automatically powers off the goggles when flipped up, preserving battery life. The power system is flexible: a single CR123A battery fits internally, or an external battery box holding four CR123A batteries can be attached for extended runtime (up to 100 hours). The PVS‑31 mounts to any standard American helmet interface (Wilcox‑type) and includes a helmet bracket. Its robust construction is rated IP65 (IP67 optional), operates in extreme temperatures (-40°C to +55°C), and withstands high humidity (5%‑95%). The compact dimensions (112×105×86 mm) and light weight (<490 g with battery) make it comfortable for prolonged wear.
