ARMASIGHT by FLIR MNVD-51 3Ge Multi-Purpose Night Vision Monocular

Part Number: NSMNYX14M5G9EA1



The Armasight by FLIR MNVD is a multi-purpose night vision monocular. It can be hand held, head mounted, helmet mounted, or weapon mounted. With a 51° field of view (FOV), it provides a large visual field without needing to move the monocular. The MNVD 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 MNVD can run up to 40 hours.
Experienced professionals know that nighttime scenes appear much more natural when displayed in black and white, as opposed to the typical “night-vision green.” Gen 3 “Ghost” White Phosphor IITs are characterized by high-contrast screens that offer black and white image, which provide clearer details, better contrast, and more distinct shapes and shadows.
