FL30-180mm F/0.8-1.2 LWIR Uncooled Continuous Zoom Lens For 640x512-17um

Description of Infrared Zoom Lens:

1. Basic principle:

Utilize the movement of two or more lens groups in the optical system to change the combined focal length of the optical system while keeping the position of the image plane unchanged, and the image quality is always kept good during the zooming process.

2. Optical system:

Mechanical compensation zoom system: each moving component moves relatively complexly according to different motion rules, and finally achieves the purpose of preventing image plane movement. Mechanical compensation zoom lens: one group of lenses moves linearly (commonly known as the zoom group) to change the focal length, and the other group of lenses (commonly known as the compensation group) makes a small amount of non-linear movement to compensate for the displacement of the image plane to achieve both zooming of the optical system. And the position of the image plane is required to be stable. The zoom group is generally a negative lens group, and the compensation group can be a positive lens group or a negative lens group. The movement direction of the compensating lens group is different from that of the variable power lens group and the speed is not constant, but their relative motion has a strict corresponding relationship, and each lens group realizes relative motion through a complex cam mechanism. The focal length of this type of zoom lens changes continuously within a certain range.

Applications of infrared lenses include:

1. Airborne (UAV)

2. Security and Surveillance

3. Maritme and Naval Surveillance

4. Thermal Imaging Devices

5. Defense

6. Thermography

7. Enhanced Vision
