Dielectric Mirror High Power 50mm Diameter 248nm Wavelength

TFMHP-50C08-248

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.

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.
