22.58-500mm F/5.5 MWIR Continuous Zoom Lens For 640X512,15um

Feature of Cooled Continuous Zoom LWIR Lens:

Wavelength 3.7-4.8um, focal length range 22.58-500mm, aperture 5.5 medium-wave cooled continuous zoom infrared optical lens, AR outer coating, imaging range 1m~∞, 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.

Infrared detection technologies such as infrared thermal imaging are widely used in military, industrial and civilian fields. For detectors, uncooled detectors have the advantages of low price, small size, light weight, and low power consumption, but their sensitivity is low, while medium-wave cooled detectors are more expensive than similar long-wave detectors due to their high sensitivity. higher. The more obvious advantage is that in order to meet the search and tracking of long-distance targets, the use of medium-wave cooled infrared lenses on handheld infrared observation equipment has a good application prospect.

Generally, infrared zoom imaging systems are divided into two types: continuous zoom and fixed-range zoom, and fixed-range zoom is mainly based on two-speed and three-speed zoom. The continuous zoom infrared optical system is used in the airborne electro-optical reconnaissance system, which can not only provide the pilot with the best situational awareness when cruising and searching, but also adjust to a small field of view to aim and track when a target is found. It is very beneficial to search and track high-speed moving targets to maintain image continuity during field of view switching. This system solves the problem of losing fast-moving targets during the time interval between two-speed and multi-speed lenses. A defect, therefore, is widely used in airborne optoelectronic reconnaissance equipment.
