Liquid Crystal Polarization Rotators — Model LCPR-10-635
Single-wavelength (635 nm) liquid crystal polarization rotator: LCVR + polymer true zero-order QWP combination for continuous >180° rotation of linearly polarized light, Ø10 mm clear aperture.
Overview
The LBTEK Liquid Crystal Polarization Rotator (LCPR) is fabricated based on a Liquid Crystal Variable Retarder (LCVR) and a polymer true zero-order Quarter-Wave Plate (QWP), mounted in a mechanical housing with attached wiring.
Composed of a liquid crystal variable retarder and a polymer true zero-order quarter-wave plate, supplemented with a mechanical housing and wiring.
LBTEK enables continuous polarization direction rotation of the incident linearly polarized light over 180° without relying on mechanical structures, while maintaining the emergent light's energy unchanged.
Key Features
- Fast-axis alignment at 45° between the liquid crystal variable retarder and the quarter-wave plate, single-wavelength device
- Continuous polarization direction rotation of the incident linearly polarized light over 180°
- Extinction ratio of emergent linearly polarized light >1000:1
- Operating wavelength: 635 nm, compatible with voltage controller LCVRC-2K25
- Custom services for parameter specifications available
Applications
- Continuous, vibration-free polarization direction rotation for 635 nm linearly polarized light.
- Paired with LBTek voltage controller LCVRC-2K25 for electrical control of polarization state.
