Classification of zoom lensThere are two types of zoom lenses, optical compensation, and mechanical compensation.In an optically compensated zoom lens, two or more alternate lenses are connected and move together relative to the lens between them. This structure simplifies the mechanical structure a

The Future Trends of infrared lens1. AthermalizationVarious methods are currently used to achieve athermalization. Using a combination of materials such as zinc sulfide, zinc selenide, and germanium can provide some passive optical athermalization. Hybrid passive / active mechanical athermalization

Cleaning IR Lens & infrared lens Methods:Blow the infrared lens with clean air to remove dust that floats on the IR lens surface;Dust with specific lens brush; Apply solvent directly to the pad, and slow, even, light pressure working from edge to edge across the optic allowing solvent to evaporate directly behind pad.

The infrared lens of infrared thermal imaging detector is also very important.The infrared thermal imaging detector works by using the electromagnetic waves emitted by the object.
