Broadband Metallic Mirrors
Broadband metallic mirrors have a thin layer of a metal coating to provide an abrasion-resistant surface while maintaining performance. These are best suited for applications that required broadband reflection. Due to the oxidation property of silver, metallic mirrors are suitable in the low-humid environment. Wavelength Opto-Electronic offers Metal Mirrors in two protective coatings (Aluminium and Silver) with high surface quality and flatness.
