A polarization beam splitter (PBS) and combiner includes a multilayer birefringent stack adjacent to a dichroic coating, sandwiched between glass prisms. This configuration overcomes the reflected wave distortion associated with a conventional multilayer birefringent cube PBS while maintaining excellent polarization performance. An exemplary application of the PBS and combiner is in a four-port LCOS imaging system. LCOS projection architectures based on the PBS are also disclosed.
