Ultiquest Technology offers dielectric mirrors which designs are much more resistant to laser damage than typical mirrors and are suitable for use with high power laser systems.
They are manufactured using all dielectric multi-layer coatings of alternating high and low index layers. These are specifically designed for use at 45 or 0 degrees angle of incidence.

| NOTES! |
|
|
Reflectance of dielectric mirrors vary according to the polarization of the input beams. S-polarization exhibits a higher reflectance and a wider reflective bandwidth than P-polarization. |
|
The coated surface of the mirror that rear surface is polished is indicated with an arrow on the side of substrate. |
|
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 be different with production lots. |
|
The surface flatness is the reflected wavefront distortion of the surface befor coating. |
|
Be sure to wear laser safety goggles when checking optical path and adjusting optical axis. |
