All dielectric coating designs are much more resistant to laser damage than typical mirrors and are suitable for use with high power laser systems.

Details

◦All Dielectric Mirrors for High Power Laser are manufactured using dielectric multi-layer coatings of alternating high and low index layers.
◦The Mirrors are specifically designed for use at 45 degrees (AOI).
◦All dielectric coating designs are much more resistant to laser damage than typical mirrors and are suitable for use with high power laser systems.
◦Mirrors for YAG lasers are also available.

Guide	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. WEB Reference Catalog Code/W3800 Also available are our surface flatness guarantee (HTFM) mirrors with accuracy guarantee after surface coating. WEB Reference Catalog Code/W3002 Please refer to here for "Wavelength Characteristic Data (Reference Data, Transmittance: T[%]) " for each wavelength.
Remark	-
Attention	Reflectance of dielectric mirrors will vary according to the polarization of the input beams. 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 of laser line mirrors are different according to the polarization of input beams. S-polarization has the high reflectance and the wide reflective bandwidth compared with p-polarization. The reflectance in the specifications list is that of random polarization or (p-polarization reflectance + s-polarization reflectance) / 2. The reflectance curves are based on actual measurements and may vary with 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.
