Elliptical Mirror, 33.02 x 46.7 mm, 532 nm Dielectric Laser Line

Elliptical Nd:YAG Laser Line Dielectric Mirrors

The 13E20DM.11 Laser Line Dielectric Elliptical Mirror is a highly efficient reflector optimized for the 532 nm wavelength. This 1.30 inch (33.02 mm) minor axis, 1.838 inch (46.70 mm) major axis, elliptical mirror is made from a 9.37 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.
