Combining the performance of a military thermal sight and the precision of a riflescope, the IR Hunter MKII 640 2.5x-20x Thermal Weapon Sight features a BAE Systems MicroIR uncooled Vanadium Oxide microbolometer with spectral a range of 8-12µm and a pixel pitch of 12µm. It allows users to see hot and warm objects in complete darkness without the need for external illumination. You will detect and see wild animals, livestock, humans, running engines, and other heat sources during day or night. The shock-resistant 35mm, f/1.2 system features Ophir Optics germanium lens with an anti-scratch, Diamond-Like Carbon protective window. The lens is anti-reflection coated for improved transmission of infrared light and thermally stabilized for improved resolution.

To add versatility to the device, the built-in electronics offer a digital zoom of up to 20x. You can view images and aim on target using the built-in 640x480 OLED display or use a video output port to connect to external screen or recording device with a choice of 60Hz or 30Hz frame refresh rates. To provide improved visibility, the sight comes with a number of digital imaging features such as Digital Contrast Enhancement, Enhanced Target Recognition, and three digital reticle patters.

The housing is made of 6061-T6 aluminum alloy with black anodizing finish. It provides shock-resistant and waterproof performance and protects the sight from submersion to 3' for 15 minutes. It also features an ergonomic and lightweight design with knurled adjusters and windage and elevation knobs for a tight grip. The included high-precision LaRue LT681 mount has a single-lever quick release system for strong attachment to Picatinny rails. Also included are two lithium CR-123 batteries, soft storage case, and shuttered eyeguard.
