NVS 6 The NVS 6 aviator night vision goggles feature binocular viewing and were designed specifically for use by helicopter pilots during night flight missions. Whether the mission involves fixed or rotary wing aircraft, flight crews can now benefit from the NVS 6 aviator system, specifically adapted to their needs. The goggles allow the aviator to navigate at the nap of the earth, flying off, landing and other operations that are practically impossible or extremely dangerous at night without the use of Alight source. Improved situational awareness and system performance, in addition to ergonomic and technological enhancements, willbenefit both law enforcement and civil operators. Adjustable 25 mm eyepieces provide improved eye relief enabling excellentviewing regardless of the eyepiece positioning. Ergonomically designed interface controls including interpupillary adjustments and vertical, fore-aft, and tilt adjustments allow improved viewing of the entire system field of view (40 degrees). The lightweight binocular can be mounted to a variety of aviator helmets.
