The cooled long - wave infrared continuous zoom thermal imager is equipped with a Stirling cooled long - wave detector with a resolution of 640 × 512 and a pixel size of 15μm. It is respectively equipped with continuous zoom long - wave infrared lenses with focal length ranges of 40mm - 200mm and 50mm - 340mm. The thermal imager is equipped with various intelligent image processing algorithms such as adaptive non - uniformity correction, image noise filtering, automatic enhancement, and multi - temperature adaptation. The infrared lens has functions such as electric zoom, electric focusing, and one - click focusing. The infrared lens can continuously zoom and image clearly throughout the process; during the zoom process, the overall optical axis consistency is no more than 2 pixels, and the optical axis repeatability is no more than 1 pixel; it has the advantages of excellent grayscale stability and a wide grayscale response range, and can be applied to various platforms such as  photoelectric theodolites and photoelectric turrets.

• Product Features Stable optical axis during continuous zooming, with a consistency deviation no more than 2 pixels;

• Wide grayscale response range, not less than 2500 - 13500, and the response linearity is better than 1.5%;

• Has strong environmental adaptability, can work stably in high and low temperature environments for a long time;

• The measured radiation characteristics are diverse, matching with continuous rotating polarizers, 4 kinds of attenuation

• sheets, and 4 kinds of narrow - band filters.
