Narrowband Laser Mirror is designed with reflectivity R > 99.5% for Nd YAG laser applications.
The Narrowband Mirror is 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.
