The LWIR zoom cooled thermal imager (640) is equipped with a Stirling cooled detectors with 640×512 resolution and 15μm pixel, and also 40mm~200mm LWIR continuous zoom lenses. The thermal imager has a working band of 7.7μm~9.3μm. The product boasts a variety of intelligent image processing algorithms such as adaptive non-uniformity correction, image noise filtering, automatic enhancement, automatic dimming, multi-background correction and multi-temperature adaptation. The IR lens features the functions of electric magnification, electric focusing, one-button focusing and electric lens cap. The lens zooms continuously and generates clear imageries; during the entire zooming course, the optical axis has consistency of no more than 2 pixels, and repetition accuracy of no more than 1 pixel; the thermal imager has a compact structure, a small size, a light weight, good self-protection and environmental adaptability, and can be directly applied to various photoelectric theodolites, photoelectric turrets and other platforms in the field.
