Night Vision Devices amplify ambient light, such as starlight or moonlight, using Gen 3 image intensifier tubes to provide visibility in near-total darkness.

They come in several form factors, including monoculars, binoculars, goggles, and clip-ons, and can be used hand-held, head-mounted, or helmet-mounted depending on the application. These devices adapt to changing light conditions with features like Manual Gain Control (MGC) and automatic brightness adjustment.

Additional features include bright light shut-off for tube protection and a built-in IR illuminator with spot/flood adjustment for improved clarity. The clip-on model is specifically designed for long-range shooting, offering visibility up to 1,000 metres for precision in low-light environments.
