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.

characteristic:

1、Ultra thin lenses, double-sided coated with transparent film (with a transparency of up to 99.85%, and a significant increase in welding strength can be felt).

2、The wavelength of 1064 is suitable for any YAG laser welding machine with a wavelength of 1064.

3、The material is made of K9 crystal material, which has undergone exclusive "chemical tempering" treatment (with higher hardness, natural vertical drop at a height of 0.8 meters to ensure no damage, and can withstand high temperatures for a long time)

Common specifications include:φ50*2、φ78*3、φ133*5、φ134*3;Other specifications can be customized.
