A novel compensation scheme for correcting geometrical depolarization affects in cube polarizing beamsplitters is presented. The low cost, oblique, uniaxial birefringent components used can significantly improve system performance, e.g. the contrast of LCoS projection systems. The scheme is generally applicable to all mirror‐like beamsplitting elements whose performance can be improved by minimizing geometric polarization mixing.
