The 640 x 512 TWS-13D-L Thermal Weapon Sight from N-Vision allows the operator to detect, recognize, and identify targets in all conditions, day or night. It comes with a 50mm lens and a 640 x 512 VOx thermal detector with 17µm pitch. It features a rugged and lightweight housing, which is constructed from aircraft grade 6061-T6 aluminum.
The weapon sight offers easy operation with clearly marked digital controls. It includes four reticle patterns for individual weapons with corresponding zero, color, brightness, and contrast. Polarity is displayed in either white hot or black hot options to suit the tactical scenario. The weapon sight offers 2x and 4x digital zoom that magnifies the visual scene. It also allows the operator to photograph targets and save the images on the internal storage and then transfer them to a computer using a USB cable.
