The 10E20AL.2 Broadband Metallic Elliptical Mirror is an excellent general purpose, broadband reflector. This 1.0 inch (25.4 mm) minor axis, 1.41 inch (35.9 mm) major axis, elliptical mirror is made from a 6.0 mm thick N-BK7 substrate. The AL.2 UV enhanced aluminum coating is a durable, broadband UV reflector with average reflectivity greater than 90% from 250 – 600 nm. The aluminum film is overcoated with UV transparent magnesium fluoride to prevent oxidation of the metal. This mirror has a λ/10 surface flatness and a 40-20 surface quality.
