Laser Optics - Optical Mirrors - Laser Line Mirrors

Laser Line Mirrors

Laser line mirrors are designed with reflectivity R > 99.5% for Nd YAG laser applications. The laser line mirrors are available with us at fundamental line 1064nm with their harmonics 532nm, 355nm, and 266nm for 45° angle of incidence. These mirrors have a higher damage threshold, high optical quality, and are suitable for beam-guiding applications. Any different wavelength laser lines and different angles of incidence are provided upon request.
