  • Polarisation rotator with small induced ellipticity
    Patent number: 9025095
    Abstract: The invention relates to a polarization rotator with small polarization ellipticity. The rotator includes a first optical unit (401) and a second optical unit (402) on a common optical axis. The first optical unit (401) is formed by a rectilinear polarizer (205) and a first quarter-wave plate (210), where the polarization direction of the polarizer is a bisector of the neutral axes of the quarter-wave plate. The second optical unit (402) is formed by a variable-delay plate (220) and a second quarter-wave plate (230), where the neutral axes of the second quarter-wave plate are bisectors of the neutral variable-delay plate axes.
