Aluminum Mirror, Pinhole-Free, Borofloat, 25.4 mm, λ/10, 450-700 nm

The 10D20ER.1-PF Pinhole-Free Broadband Aluminum Mirror was developed to be virtually free of pinholes to significantly decrease scattering effects. Our Pinhole-Free mirrors are ideal for sensitive applications which require an economical broadband reflector. This 25.4 mm (1.0 inch) diameter mirror is made from a 6.0 mm thick Borofloat® 33 substrate. Borofloat has low thermal expansion and is an excellent substrate for most applications. The ER.1-PF enhanced aluminum coating may be used wherever a broadband visible and near infrared reflector is needed. A multilayer dielectric stack deposited over the aluminum film boosts reflectance and improves the durability of the coating. The 10D20ER.1-PF has an average reflectivity greater than 93% from 450-700 nm. This mirror has a λ/10 surface flatness and a 15-5 surface quality.
