These laser mirrors are designed for specific wavelength laser applications where low wavefront distortion, low scattering and high reflectivity are usually important. These narrowband reflectors are for several wavelengths and sizes.

◦Dielectric multi-layer coating does not have absorption like Aluminum coatings and provide higher than 99% reflectance except some mirrors for UV wavelength use are provide 95% reflectance.
◦These coatings are much harder and provide higher laser damage threshold than Al+MgF2 coating.

▶Please consult our Sales Division for assistance in your selection and for customized products. (customized on outer diameter, wavelength characteristic, etc.) Please use the inquiry sheet.
W3800
▶Also available are our surface flatness guarantee (HTFM) mirrors with accuracy guarantee after surface coating.
W3002

Attention

▶The un-coated rear surface of the mirror is polished and the arrow on the side of the substrate points towards the coated surface.
▶Reflectance values of laser line mirrors are different according to the polarization of input beams. S-Polarization has high reflectance with a wide reflective bandwidth when compared to P-Polarization. The reflectance specification listed is at random polarization or (P-Polarization reflectance + S-Polarization reflectance) / 2.
▶The reflectance curves are based on actual measurements and may be vary by production lots.
▶Be sure to wear laser safety goggles when checking optical path and adjusting optical axis.
▶The surface flatness is the reflected surface wavefront distortion before coating.
