10.6μm : CO2 Optics : Phase Retarders

Silicon & Copper Phase Retardation Reflectors

Silicon & Copper Phase Retardation Reflectors

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

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