TWS13D Revision A Thermal Weapon Sight

TWS13D Revision A Thermal Weapon Sight

  • New for 2023
  • 640 X 512,  12 micron Thermal Core
  • 50mm Lens

The newly released TWS13D Revision A 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 TWS13D can be used on a variety of long range sniper rifles and machine guns up to .50 caliber, such as M2 and M240.

N-Vision Optics’ TWS13D Revision A 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 TWS13D Revision A generates superior IR images and ensures target acquisition at the maximum possible ranges.

Ideal for medium to long range weapon systems, the TWS13D Revision A is equipped with a 640X512, 12-micron core, 50mm objective lens, allowing for greater detection, recognition, and identification ranges. It includes four reticles selectable and adjustable to boresight (M240B and M2 reticles included).
