Specifications:
Material: Silicon (Si) Single Crystal
Diameter Tolerances: +.000” -.005”
Thickness: ±.010”
Flatness: 1/40 wavelength @ 10.6 µm
Parallelism: < 3 minutes of arc
Surface Quality: < 40/20 scratch dig Laser Finish
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 fo maintain the circular polarization.
