The AGM NVG-40 NW1 night vision binocular is a two-channel night vision system. With a viewing angle of 40 °, it provides a large field of view without having to move the binoculars. The NVG-40 uses advanced multi-coated optics and is designed for durability thanks to its compact composite housing. Powered by a single AA alkaline battery or a CR123A battery, the NVG can run for up to 20 hours. Also equipped with a built-in infrared illuminator for reading in the dark. For hands-free NVG use, it can be mounted on many different mounts, such as AN / PVS-7D, AN / PVS-14, AN / PVS-7A / C, AN / PVS-15, and AN / PVS-18 Mounts, or fastening with a mini-rail. The NVG interface shoe (pre-installed) is used to install the NVG on a standard swallowtail headset and helmet mount.
