TWS13C Thermal Weapon Sight

TWS13C Thermal Weapon Sight

  • 640 X 512,  17 micron FLIR Thermal Core
  • 35mm Lens

The TWS13C 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 TW13C can be used on a variety of medium range weapons systems up to 7.62 caliber including the M4, M4A1 and M16A2.

N-Vision Optics’ TWS13C 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 TWS13C  generates superior IR images and ensures target acquisition at maximum possible ranges.

The TWS13C features a 640X512, 17 micron core with a 35mm objective lens optimal for scenarios where field of view is a significant factor. TW13C comes with four reticles selectable and adjustable to boresight (including M4, M4A1 and M16A2).
