Our Broadband Dielectric Mirrors are made from JGS1 fused silica, ensuring high durability and low thermal expansion. They are available with two coating options: 400 - 750 nm and 750 - 1100 nm, providing excellent reflectivity across a broad wavelength range. With an average reflectance (Ravg) greater than 99% for both S- and P-polarization at angles of incidence from 0° to 45°, these mirrors deliver superior performance for various optical applications. We offer them in Ø1/2", Ø1", and Ø2" sizes to accommodate different system requirements.
