Newport MKS UV Aluminum Mirror Pack, Economy, Borofloat, 12.7 mm, λ/10, 250-600 nm, Qty 10 05D620AL.2-PK

This is a 10-pack of the Economy UV Enhanced Aluminum Broadband Mirrors. By taking advantage of advanced polishing techniques and our high-volume manufacturing, these mirrors are truly cost effective. These 12.7 mm (1/2 inch) diameter mirrors are made from a 3.1 mm thick Borofloat® 33 substrate and are 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 λ/10 surface flatness and a 40-20 surface quality.
