Fused silica optical window

fiber laser protection window The main function of optical fiber laser protection window is to protect the focusing lens, to prevent the lens from damage by the splashing objects. By periodic replacement of the protection window, the accuracy of processing can be ensured. The high damage threshold (>15J/cm2)@ 1064 nm AR coating on the window can effectively increase its transmittance , reduce the energy loss and improve the quality of the product being processed. It is widely used in laser cutting machine, laser welding machine and other laser equipment.
