Aluminum Mirror, Zerodur, 25.4 mm, λ/20, 450-700 nm

High-Performance Zerodur Metallic Mirrors

The 10Z40ER.1 Broadband Aluminum Mirror is an excellent general purpose, broadband reflector. This 25.4 mm (1.0 inch) diameter mirror is made from a 6.0 mm thick Zerodur substrate. Zerodur, a glass-ceramic material, exhibits nominally zero thermal expansion which provides extra stability for applications requiring diffraction limited performance. The ER.1 enhanced aluminum coating may be used wherever a broadband visible and near infrared reflector is needed. A multilayer dielectric stack deposited over the aluminum film boosts reflectance and improves the durability of the coating. The 10Z40ER.1 has an average reflectivity greater than 93% from 450-700 nm. This mirror has a λ/20 surface flatness and a 10-2 surface quality.
