The 20Z40DM.10 Laser Line Dielectric mirror is a highly efficient reflector optimized for a narrow 1030 to 1090 nm wavelength range. This 2 inch (50.8 mm) diameter mirror is made from a 12.7 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 DM.10 coating is designed for use with low-power Nd:YAG lasers and has a center wavelength of 1064 nm. The coating achieves greater than 99% reflectance, from 0–45° angle of incidence, for any polarization. This multilayer dielectric coating is extremely durable, making it resistant to damage from repeated cleaning. This mirror has a λ/20 surface flatness and a 10-2 surface quality.
