Night Optics USA Micro 2 640 (20mm)

The MICRO 2 640 (20MM) is a thermal imaging monocular made by Night Optics USA and is part of the Micro 2 series. It utilizes a 640 x 480 pixels thermal core with a refresh rate of 30Hz and features a 20mm lens, giving you a field of view of 8 x 11 degrees.

Standard features include 2 thermal core options - 336x256 and 640x480, a brilliant 800x600 AMOLED display, 9, 30 or 60hz refresh rate (Configured by Night Optics), 4 polarity options, accelerometer for image rotation, video-out and external power through a single input cable, All-in-one mount for head, helmet, tripod and weapon, 1x, 2x and 4x digital magnification and a sealed, shockproof housing.

The Micro 2 operates on a single 3v CR123. The lens cover is built into the housing and not only protects the high-grade 20mm focusable germanium optics, but is also used when calibrating the core. Core calibration is typically needed only once after power-up unlike other thermal cores that auto-calibrate constantly. This features makes operation quiet and preserves battery life.

The Micro 2 is an excellent system for Law Enforcement and Military professionals as well as hunters, wildlife researchers and outdoor enthusiasts.
