The main functions of the fiber laser protective lens are to protect the focusing lens, to prevent splashes from sputtering on the lens and causing damage to the lens, and to ensure the processing accuracy requirements by regularly replacing the protective lens. Coating the lens with 1064 antireflection coating with a high damage threshold (>10Jcm2) can effectively increase the transmittance of the lens, reduce energy loss, and improve the quality of processed products. Widely used in laser cutting machines, welding machines, and other laser equipment.
