The 10D20DM.8 Laser Line Dielectric mirror is a highly efficient reflector optimized for a narrow 1520 to 1580 nm wavelength range. This 1 inch (25.4 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.8 coating is designed for use with diode lasers and has a center wavelength of 1550 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.
