Introducing quarter wave reflective phase retardation coated mirror into the beam delivery path eliminates curve variations by converting linear polarization beams to circular polarization.
Circular polarization occurs when S and P polarization are equal and uniform cuts are achieved regardless of cut direction.
Typically used as the last mirror before the focusing lens.
Phase Shift: <2.0° between P and S polarization
for 9.3-9.4µm operation only @ 45° Angle Of Incidence
Reflectance: > 99.6% average @ 9.3-9.4µm
Absorption: < .40% @ 9.3-9.4µm
Coating optimized to maintain low phase shift in beam delivery systems
where a 90° phase retarder exists to maintain the circular polarization.
