Laser Line Mirrors are dielectric reflectors with optimised performance at stated laser wavelengths. Dual band laser mirrors are offered for applications where reflection of two laser lines is needed.
Our laser mirrors are made from BK7 or quartz and coated with dielectric multilayer coating. The achieved high polishing quality is also important for low wave front distortion, low scattering and high damage threshold.
