Laser Protective Window, R<0.2% (CAT#: STEM-AL-7940-ZJF)

This product is intended for protective transmission in high-power laser systems. It is designed to transmit the required laser wavelength while shielding downstream optics. The construction uses BK7 or fused-silica substrates with low-reflection coating. Its optical arrangement provides high transmission with very low residual reflection. The design emphasizes high damage resistance and low absorption. The component can be integrated into laser processing heads and protective optical ports. The stated configuration is based only on the optical, mechanical, and operating information supplied in the source. Overall, the product provides a replaceable protective interface for high-power laser optics.
