The 07D20ER.4 Broadband Metallic Mirror is an excellent general purpose, broadband reflectors. This 3/4 inch (19.05 mm) diameter mirror is made from a 4.57 mm thick Borofloat® 33 substrate. Borofloat® 33 glass has low thermal expansion and is an excellent substrate for most applications. The ER.4 protected gold coating is ideal for applications requiring broadband reflectance in the near IR to the far IR. A multilayer dielectric overcoat provides protection to the gold from the environment. Average reflectivity is greater than 96% from 650–1700 nm and greater than 98% from 1.7–2.0 µm. This mirror has a λ/10 surface flatness and a 15-5 surface quality.
