UV Aluminum Mirror, Borofloat, 76.2 mm, λ/10, 250-600 nm

The 30D20AL.2 Broadband UV Enhanced Aluminum Mirror is an excellent general purpose, broadband reflector. This 76.2 mm (3.0 inch) diameter mirror is made from a 14.7 mm thick Borofloat® 33 substrate which is coated with the AL.2 aluminum coating. Borofloat® 33 has low thermal expansion and is an excellent substrate for most applications. 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 15-5 surface quality.
