Midwave Infrared Zoom Lens

Midwave infrared zoom lens is mainly used in the detection and recognition of thermal infrared targets, which can realize the wide range search of targets in a large field of view and the recognition and tracking of targets in a small field of view. The continuous zoom lens can continuously zoom in, which is more conducive to the detection and identification of low, small and slow targets.

It can work around the clock under conditions such as low illumination and bad weather, and can effectively make up for the shortcomings of visible light imaging systems limited by conditions such as light intensity.
