TWS13A Thermal Weapon Sight

TWS13A Thermal Weapon Sight

  • 336 X 256,  17 micron FLIR Thermal Core
  • 35mm lens

N-Vision Optics’ newly redesigned TWS13 dedicated thermal weapon sight line-up provides operators with a significant advantage in detecting, observing, and engaging targets in all conditions, day or night. Combining a rugged and lightweight hi-tech composite material housing with advanced thermal imaging technology, the TWS13 series of weapon sights generate superior IR images and ensures target acquisition at maximum possible ranges.

Designed for use with CQB and medium-range weapon systems, the TWS13A features a 336X256, 17 micron core with a 35mm objective lens optimal for scenarios where field of view is a significant factor.

The TWS13 includes four reticle patterns custom-tailored for individual weapons with corresponding zero, color, brightness and contrast. Polarity is displayed in either white hot or black hot options to best suit the tactical scenario. Standard 2x and 4x digital zoom enables clear identification of targets before engaging them. The TWS13 allows the user to photograph targets, save images to internal storage and later download them to a computer via USB cable.
