Quick Liquid Crystal Variable Retarders — Model QLCVR-F20-A
2-inch full-wave QLCVR for 400-700 nm, Ø20 mm clear aperture, 21 ms rise time.
Overview
Nematic liquid crystal/ITO glass, anti-parallel liquid crystal cell, with mechanical housing and wiring. Uniform in-plane alignment via polyimide layer rubbing; tunable retardance from tens of nanometers to λ/2 via externally applied AC electric field (DC not allowed).
Key Features
- Functionality as polarization modulator or pure phase retarder
- Faster response time with significantly improved speed versus previous versions
- Operating wavelength λ: 400-700 nm/700-1100 nm/1100-1700 nm optional
- Clear aperture: Ø10 mm/Ø20 mm optional
- Retardation: half-wave/full-wave/multi-wave liquid crystal variable retarder optional
- Compatible with voltage controller LCVRC-2K25
Applications
- Polarization Modulator: Polarization direction of incident linearly polarized light should be at 45° angle to fast axis for widest adjustment range.
- Pure Phase Retarder: Polarization direction of incident linearly polarized light should be at 0° angle to fast axis.
