Feature of Cooled Continuous Zoom LWIR Lens:
Wavelength 3.7-4.8um, focal length range 20-450mm, aperture 5.5 medium-wave cooled continuous zoom infrared optical lens, AR outer coating, suitable for 640x512 medium-wave cooled detectors. The product performance is stable and can be used in the working environment of -40℃~+60℃.
The fixed-focus infrared lens is widely used and simple in design, but it cannot meet the needs of large field of view search, small field of view tracking or identification, so its use is limited; dual-field or multi-field of view infrared lenses can meet large field of view search, small field of view Field tracking or recognition, but it is easy to cause the target to be lost when the field of view is switched, so the use is flawed; 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 continuously changing during the zooming process. Big or small, there are obvious advantages in use.
Common lens materials for infrared lenses:
Ge (Germanium) IG 4/5/6, IRG24/25/26(Chalcogenide), ZnSe(Zinc Selenide), ZnS(Zinc Sulfide), Si(Silicon), CaF2（Calcium Fluoride），BaF2(Barium Fluoride),etc.
Common scenarios of infrared lens:
1. Airborne (UAV)
2. Security & Surveillance
3. Maritime & Naval Surveillance
4. Thermography
5. Thermal Imaging Devices
6. Defense
7. Enhanced Vision
