Overview
Polarization gratings are fabricated from liquid-crystal-polymer birefringent material on N-BK7 glass substrates in a sandwich structure. Model PZGS25-5-488 operates at 488 nm with a phase cycle p of 5 μm over a clear aperture of Ø20 mm, giving a typical deflection angle of 5.60 °.
Applications
- Polarization-selective beam splitting and combining
- Diffractive beam steering and deflection
- Polarimetry and polarization-state analysis
- Structured illumination and interference experiments
