Thermal Imaging Weapon Sights


OE-TWS, is a rugged, lightweight and Powerful Thermal Weapon Sight with a quick release, for military and law enforcement use.
OE-TWS, is ideal for long-range human target detection in distance of up to 2 kilometer, as well as reconnaissance and surveillance, perimeter security, wildlife observation and control, and a wide variety of other applications.

While night vision technology relies on amplification of ambient light or assisting illumination, thermal devices are completely passive, sensing extremely minute temperature differentials. The rugged thermal sight combines a highly sensitive Detector with real-time image processing and lightweight, waterproof housing. Sensitive not less than 50mK, the detector’s 8-12μm spectral response ensures the widest possible thermal coverage.
