The 60D20DM.11 Laser Line Dielectric mirror is a highly efficient reflector optimized for the 532 nm wavelength. This 6 inch (152.4 mm) diameter mirror is made from a 23.5 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 20-10 surface quality.
