Laser line mirrors are dielectric reflectors with an optimized performance at stated laser wavelengths. Our laser mirrors are made from quartz and coated with multilayer dielectric or IBS coating. High polishing quality of the mirror substartes is also important for low wave front distortion, low scattering and high damage threshold.
Dielectric UV fused silica laser line mirors cover a wide range of laser applications in UV, VIS and NIR spectra.
