25-250mm F/4.0 MWIR Cooled Continuous Zoom Lens For 640x512-15um

Feature of Cooled Continuous Zoom LWIR Lens:

Wavelength 3.7-4.8um, focal length range 25-250mm, aperture 4.0 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 imaging technology is a new high-tech technology that is very needed by all branches of the military. The infrared detection system has the characteristics of good environmental adaptability, good concealment, strong anti-interference ability, and can identify the camouflaging target to a certain extent, and the equipment is small in size, light in weight and low in power consumption, so it is widely used in the military in infrared night vision, infrared reconnaissance and infrared guidance.

Prime focus infrared lens is widely used and simple in design, but it can not meet the requirements of large field of view search, small field of view tracking or recognition, and its 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 cause target loss when switching field of view, and there are defects in use. 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 enlarged or enlarged during the zoom process. Small size, 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
