    Abstract

    We demonstrate a wavelength-independent tunable liquid crystal (LC) polarization rotator using two nematic LC retarders for the spectral range from 450 to 1000 nm and wider. The first LC device with tunable retardation determines the rotation, while the second acts as an LC variable quarter-wave plate. Integration with tunable optical filters produces a modality for great potential in spectropolarimetry.
