The main function of fiber laser protective lenses is to protect the focusing lens, prevent splashing objects from damaging the lens, and ensure the accuracy requirements of processing by regularly replacing the protective lenses. Coating the lens with a 1064 anti reflective film with a high damage threshold (>15Jcm2) can effectively increase the transmittance of the lens, reduce damage energy loss, and improve the quality of processed products.

All lenses are made of imported crystal materials that have been finely processed through cutting, grinding, polishing, coating, and other processes.

Common specifications include:φ22.35*4、φ30*5、φ34*5、φ35*4、φ36*5、φ37*7、φ55*9；Other specifications can be customized.
