Dielectric Mirror, Broadband, Zerodur, 25.4 mm, 700-950 nm

High-Performance Zerodur Dielectric Mirrors

The 10Z40BD.2 Broadband Dielectric Mirror is an extremely versatile mirror for laboratory applications and highly efficient over a broad wavelength range. This 1 inch (25.4 mm) diameter mirror is made from a 6.0 mm thick Zerodur substrate. Zerodur is a glass-ceramic material where thermal expansion is nominally zero. This extra stability can be critical for applications requiring diffraction limited performance. The BD.2 coating offers high reflectance for near infrared diode laser applications. The BD-2 coating is extremely durable and will withstand repeated cleaning. This mirror has a λ/20 surface flatness and a 10-2 surface quality.
