Sights and Night Vision Devices

Sights and Night Vision Devices

Night vision devices provide observation and aiming in natural night light conditions (starlight and moonlight). NVDs use the principle of image intensification. An optical system containing a lens, an IIT (Image Intensification Tube), and an eyepiece collects the available light reflected by the observed objects and projects the intensified image into the operator's eye. The products use IIT  generation 2+ and 3 with green or black-and-white screens.
