This is a pack of 10 of the very popular 10D20ER.2 Broadband Metallic Mirrors. This mirror is an excellent general purpose, broadband reflectors. This 1 inch (25.4 mm) diameter mirror is made from a 6.0 mm thick Borofloat® 33 substrate. Borofloat® 33 has low thermal expansion and is an excellent substrate for most applications. The ER.2 protected silver coating is composed of a low emissivity silver film fully encapsulated by a multilayer dielectric stack to prevent oxidation. This coating has excellent broadband reflectivity in the IR, while maintaining very good performance in the visible and near IR. Average reflectivity is greater than 96% from 480–1100 nm and greater than 98.5% from 1.1–20 μm. This mirror has a λ/10 surface flatness and a 15-5 surface quality.
