This is a 10-pack of the very popular 10D20AL.2 Broadband UV Enhanced Aluminum Mirrors. These mirrors are excellent general purpose, broadband reflectors. These 25.4 mm (1.0 inch) diameter mirrors are made from a 6.0 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. These mirrors have a &lambda,/10 surface flatness and a 15-5 surface quality.
