Dielectric Mirror, Laser Line, 30.0 mm, λ/10, 1030-1090 nm

The 3MD20DM.10 Laser Line Dielectric mirror is a highly efficient reflector optimized for a narrow 1030 to 1090 nm wavelength range. This 1.181 inch (30.0 mm) diameter mirror is made from a 6.0 mm thick Borofloat® 33 substrate. Borofloat has low thermal expansion and is an excellent substrate for most applications. 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/10 surface flatness and a 15-5 surface quality.
