The AGM UNVG is a dual-channel night vision system. The UNVG uses advanced multi-coated optics and is built to last with a compact composite housing. The device can be outfitted with a Gen 2+ or Gen 3 high-performance image intensifier tube (IIT). The bright light cut-off feature ensures that the high-quality photocathode tube is protected. The UNVG is also equipped with manual gain control, which adjusts the image brightness, providing the highest possible image quality even in changing light conditions. The independent movement of the pods allows for single or dual eye configurations for increased operational flexibility. Each tube will automatically turn off when flipped up. Operating from a single AA alkaline battery, the UNVG can run up to 15 hours. With an external battery pack (included), the operating time increases to 50 hours! Also equipped with an integral infrared illuminator for reading in the dark. The device can be installing to a either standard dovetail type headset and helmet mount. UNVG-51 model with a 51° field of view provides a large visual field without needing to move the binoculars.
