Series ZPR Zero Phase Retardation Reflectors

These reflectors utilize a highly enhanced zero phase thin-film coatings applied to either a silicon or copper mirror substrate. This specialized design provides the basis for a low loss polarization insensitive CO2 laser mirror designed to maintain the circular polarization of the beam's delivery system. Spectral performance can be found in the table below.
