TWS13E Thermal Weapon Sight

The TWS13E dedicated thermal weapon sight uses state of the art thermal imaging core and high-end Germanium objective lens to provide users with crisp imagery in total darkness and challenging visual conditions such as smoke, fog, and dust. Constructed with extremely durable composite molded plastic and designed to meet or exceed MIL-STD-810G, the TW13E can be used on a variety of medium range weapons systems up to 7.62 caliber including the M4.

N-Vision Optics’ TWS13E weapon sight provides operators with a significant advantage in detecting, observing, and engaging targets. Combining a rugged and lightweight hi-tech composite material housing with advanced thermal imaging technology, the TWS1E3 weapon sight generates superior IR images and ensures target acquisition at maximum possible ranges.

The TWS13E features a 640X480, 12 micron core with a 25mm objective lens optimal for scenarios where field of view is a significant factor.
