The Alpha Optics AO-3240/3340 is a dual-channel night vision system. With a 40° field of view (FOV), it provides a large visual field without needing to move the binoculars. The AO-3240/3340 uses advanced multi-coated optics and is built to last with a compact composite housing. Operating from a single AA alkaline battery or CR123A battery, the AO-3240/3340 can run up to 20 hours. The device is also equipped with an integral infrared illuminator for reading in the dark. For hands-free operation, the AO-3240/3340 includes head and helmet mounting options; it can be used as binoculars, monocular, goggles, or stowed out of the way. Operated by a single gain control knob, the AO-3240/3340 utilizes features like a flip-up-turn-off, and a flip-down-turn-back-on option when mounted to a helmet.
