Spectral Performance:
Phase Shift: <2.0° between p and s polarization
for 10.6µm operation only @ 45° Angle Of Incidence
Reflectance: > 99.6% average @ 10.6µm
Absorption: < .40% @ 10.6µm
Coating optimized to maintain low phase shift in beam delivery systems
where a 90° phase retarder exists to maintain the circular polarization.
