2-inch Quick Liquid Crystal Variable Retarder, Full Wave, Uncompensated
The LBTEK 2-inch Full-Wave Quick Liquid Crystal Variable Retarder is coated with corresponding anti-reflection coatings for either the 400-700 nm or 700-1100 nm operating wavelength range. Under the control of an external AC voltage (DC voltage not allowed), it can achieve flexible adjustment of retardation between approximately 100 nm and λ.
With a clear aperture of Ø20 mm, it is mounted in a mechanical housing with attatched wiring. The housing is compatible with Ø2-inch optical component mounts, and the fast axis direction of the liquid crystal variable retarder is clearly marked for convenient optical path alignment by users.
Key Features
- Clear Aperture: Ø20 mm
- Mechanical housing compatible with Ø2-inch optical component mounts
- Operating wavelength options: 400-700 nm or 700-1100 nm
Typical Applications
- High-speed polarization modulation and switching
- Fast Stokes polarimetry and Mueller-matrix imaging
- Real-time adaptive polarization control
- Pump-probe and time-resolved spectroscopy
- Fluorescence and polarized-light microscopy
- Electro-optic phase modulation experiments
