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

◦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.

▶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.

▶Also available are our surface flatness guarantee (HTFM) mirrors with accuracy guarantee after surface coating.
W3002

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.
