The product is composed of large-aperture transmission continuous zoom lens and high-sensitivity imaging detection component. The lens has a focal length of 60mm~600mm@F2, and a maximum diameter of 314mm; the imaging detection component features 640x512@15μm resolution, and applies low-noise high-sensitivity imaging technology, with adaptive non-uniformity correction, noise filtering, wide dynamic range image intensification, automatic dimming and other intelligent image processing algorithms. It adopts vibration and impact resistance, high and low temperature resistance, sealing and other design means to ensure high reliability and reliable sealing. It can be widely used in platforms such as photoelectric theodolites and photoelectric turrets to achieve large-field target location and small-field ultra long-distance detection and tracking. The distance of detecting typical targets in the air can hit 1,500Km.

·  The ultra-long detection range is measured to be more than 12Km for humans and more than 1500Km for typical targets in the air.

· High consistency of optical axis: the total change is less than 2 pixels, realizing stable switching of field of view.
