Elliptical Mirror, UV Aluminum, N-BK7, 25.4 mm x 35.9 mm, λ/10, 250-600 nm

The 10E20AL.2 Broadband UV Enhanced Aluminum Elliptical Mirror is an excellent general purpose, broadband reflector. This 25.4 mm (1.0 inch) minor axis, 35.9 mm (1.41 inch) 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 an average reflectivity greater than 90% from 250 - 600 nm. The AL.2 aluminum coating contains a durable dielectric overcoat to prevent oxidation of the metal. This mirror has a λ/10 surface flatness and a 40-20 surface quality.
