Dielectric mirror

Multi-layer dielectric films are deposited onto optical components or substrates to alter the propagation direction of light waves, making them suitable for applications ranging from laser beam processing to instrument construction and advanced imaging systems. The dielectric mirrors produced by our company feature high reflectivity, a wide reflection bandwidth, and excellent compactness. Specific technical specifications can be customized according to customer requirements.
