Continuous Zoom LWIR lens

Continuous Zoom IR lens is used for continuous zooming rather than at one or a few distinct focal length. User would get stable image with no significant image jitter or brightness change during the zoom process. User can stop at any point during adjustment with certain magnification.

Wavelength Infrared continuous zoom LWIR lens has precision fabricating and assembling, high optical-axis stability, close to diffraction limit MTF curve. Thus our lens can provide sharp image at any magnification, with good detection, recognition and identification (DRI) ranges, suitable for a wide range of applications such as security and defense, aerial survey, smart cities, industrial & commercial monitoring and so on.

All of our continuous zoom IR lenses would go through strict optical/mechanical performance and environmental tests to ensure the best quality.

Besides standard high efficient AR coating, we can also make DLC coating or HD coating on the outer surface to protect the lens from environmental damage such as wind and sand, high humidity, salty fog and etc.
