The NO/TG-7 Thermal Goggle/Binocular is a rugged and lightweight InfraRed optic able to be hand held or mounted on a helmet or headgear. By using the 2x internal digital zoom and the optional a-focal germanium optical magnification lens, the Night Optics USA Inc. NO/TG-7 provides potent 6x long-range thermal surveillance and acquisition. The sensitive uncooled thermal detector and high resolution display provide crisp "white hot" or "black hot" images regardless of ambient conditions. While night vision technology relies on amplification of ambient light or assisting illumination, thermal devices are completely passive, sensing extremely minute temperature differentials. The NO/TG-7 Thermal Goggles therefore acquire targets in daylight and complete darkness while "seeing through" obscurants such as smoke and haze which often hinder image intensification devices. The NO/TG-7 combines a sensitive, uncooled thermal detector with the a 640x480 display integrated into the familiar PVS-7 housing, ensuring accurate images and compatibility with accessories such as Mil Spec Headgear and Helmet Mounts. The comfortable, lightweight NO/TG-7 provides a powerful advantage during both day and night operations.
