Below is a list of Series PRR: Silicon & Copper Phase Retardation Reflectors. Please call for pricing and availability.
These mirrors consist of a high effiency 1/4 wave phase reflectance thin-film coating applied to a highly polished mirror substrate. This specialized coating design changes a linearly polarized CO2 laser beam to a circularly polarized one. Spectral performance is as follows:

|
|
Si:
|
Cu: | |
| Phase Shift between P & S Polarization: | 90 deg. ±3 deg. | 90 deg. ±5 deg. |
| Reflectance@10.6 microns and 45 deg. AOI: | >98.5% Avg. | >98.5% Avg. |
| Absorption & Scatter: | < 1.5% | < 1.5% |
