Superior image quality with Leica Image Optimization

The Leica Calonox Sight is ideal for use with a riflescope and is therefore equipped with 1x magnification. Thanks to its one-piece construction, the Calonox Sight offers outstanding reliability and a consistently precise, repeatable point of impact.

With the Calonox thermal cameras, Leica continues its long, successful track record in digital image optimization, and extends its excellent reputation as a camera manufacturer. Leica’s own image processing (Leica Image Optimization – LIO™) improves the image with special algorithms, thus achieving particularly detailed color gradations, excellent contrast, and high detail resolution.

The outstanding recognition range of the Leica Calonox Sight is based on a high-end vanadium oxide (VOx) sensor with 384 x 288 pixels and 17 µm pixel size with excellent temperature resolution.
