  • Broadband Metallic Mirror 25.4 mm

    $40.00

    This used Newport 10D20ER.1 Broadband Metallic Mirror is in excellent condition with no visible defects.

    From manufacturer website: The 10D20ER.1 Broadband Metallic Mirror is an excellent general purpose, broadband reflector. This 1 inch (25.4 mm) diameter mirror is made from a 6.0 mm thick Pyrex substrate. Pyrex has low thermal expansion and is an excellent substrate for most applications. The ER.1 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. Average reflectivity is greater than 93% from 450 – 700 nm. This mirror has a /10 surface flatness and a 15-5 surface quality.
