50-300mm F/5.5 Cooled Continuous Zoom Lens For 640x512-15um Detector

Feature of Cooled Continuous Zoom LWIR Lens:

Wavelength 3.7-4.8um, focal length range 50-300mm, aperture 5.5 medium-wave cooled continuous zoom infrared optical lens, AR outer coating, suitable for 640x512 medium-wave cooled detectors. Due to the wide range of operating temperatures of handheld devices, the medium-wave cooling continuous zoom lens can be used in the working environment of -40°C~+60°C, and has a wide range of uses.

General infrared zoom system is divided into continuous zoom and fixed zoom two kinds, the prime focus infrared lens is widely used, the design is simple, but can not meet the large field of view search, small field of view tracking or recognition requirements, the use is limited; Dual-field or multi-field infrared lens can meet the requirements of large-field search and small-field tracking or recognition, but it is easy to lose the target when the field of view is switched, and there are defects in use.

The continuous zoom infrared lens can not only meet the large field of view search, small field of view tracking or recognition, but also keep the target enlarged or reduced in the zoom process, which is more widely used.
