ATN NVGOPS3142G PS31-2 NVG | 1x 18mm | Gen 2+

The ATN PS31-2 (NVGOPS3142G) PS31 Binocular Night Vision Device is a compact, lightweight dual-tube goggle designed to replace legacy BNVD systems while reducing head‑borne weight and improving center of gravity. It provides a 40° field of view and uses Generation 2+ green phosphor image intensifier tubes rated at 58–60 lp/mm resolution. The unit supports independently pivoting tube housings so operators can configure it for binocular or monocular use and stow the tubes flat against a helmet to lower profile when needed.

Typical applications include low-light navigation and technical search-and-rescue, as well as professional observation and vehicle/helmet-mounted operations where reduced weight and reliable imagery matter.
