The ATN Set of (2) 3x Lenses for PS31 is a high-performance accessory designed to convert ATN PS31 series night vision goggles into high-power night vision binoculars. These afocal lenses attach directly to the existing objective lenses of the PS31 unit, providing an additional 3x optical magnification to significantly extend the device's detection and recognition range for long-range observation. Meticulously crafted for crystal-clear visuals, this set is ideal for tactical operations, property surveillance, and wildlife observation where increased distance is required without sacrificing the depth perception provided by a dual-tube system.
