10.600nm : CO2 Optics : Phase Retarders

Metric 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.
