Laser Protective Len

Fiber laser protection lens is mainly used to protect the focusing lens, blocking the splash on the lens to cause damage to the lens, through the regular replacement of the protection lens to ensure the accuracy of processing requirements. The lens is coated with high damage threshold (>15J/cm2) of 1064nm transmission film can effectively increase the transmission rate of the lens, reduce energy loss and improve the quality of processing products.

Laser protective lenses are also called laser windows and laser dust-proof lenses. They are mainly used to protect the focusing lens and prevent splashes from splashing onto the lens and causing damage to the lens. Regular replacement of the protective lens can ensure the processing accuracy requirements. Coating the anti-reflection coating with high damage threshold (>15Jcm2) on the lens can effectively increase the transmittance of the lens, reduce the loss of damage energy, and improve the quality of processed products. Widely used in various laser processing equipment: such as laser cutting machine, laser welding machine, laser marking machine and laser engraving machine, etc.


All our lenses are made of imported quartz crystal materials through cutting, grinding, polishing, coating and other processes. We can customize various specifications of protective lenses for customers, and other specifications can be customized according to customer needs.


Features of laser protective lens

● Imported quartz crystal material, ultra-thin lens, not easy to chip and crack.

● Double-sided coated light-transmitting film (up to 99.5% light transmittance).

● Strong durability, high temperature resistance, and strong laser resistance.

● Wavelength 1064nm, wide application range.

● 45° protective full-angle design, safe and easy to use without hurting hands.

● High light transmittance, strong anti-slag resistance and long service life.
