Night Vision Goggles allow soldiers to drive vehicles, conduct maintenance, read maps, navigate, and conduct first aid during periods of darkness. The goggles come with a head-harness that allows for hands-free use of the NVGs. They can also be slung around the neck for hand-held periodic viewing.
Solder using C2 AN/PVS-504(A) Night Vision Goggles (NVGs)NVGs require no active visible or infrared light source in order to work. The Image Intensifier Tube amplifies existing light, which allows the user to function as in daylight conditions. The user can also activate an infrared illumination diode in areas of total darkness and situations requiring additional light. The NVG has one objective lens and two eyepieces. The operator can focus the objective lens from 25cm (for map reading) to infinity (for general viewing). The NVG is compatible with all Canadian army helmets as well as NBC Respirators (gas masks).
