Product Series Overview
Elliptical Nd:YAG Laser Line Dielectric MirrorsThe 13E20DM.10 Laser Line Dielectric Elliptical Mirror is a highly efficient reflector optimized for a narrow 1030 to 1090 nm wavelength range. 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.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.
