Dielectric Mirror, Laser Line, 50.8 mm Diameter, λ/10, 532 nm

Borofloat 33 Laser Line Dielectric Mirrors

The 20D20DM.11 Laser Line Dielectric mirror is a highly efficient reflector optimized for the 532 nm wavelength. This 2 inch (50.8 mm) diameter mirror is made from a 12.7 mm thick Borofloat® 33 substrate. Borofloat has low thermal expansion and is an excellent substrate for most applications. The DM.11 coating is designed for use with low-power Nd:YAG lasers and has a center wavelength of 532 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/10 surface flatness and a 15-5 surface quality.
