Abstract
For combining light from different light sources that are spatially apart, an optical system comprises a prism assembly that comprises a totally-internally-surface and a dichroic filter. The totally-internally-surface and the dichroic filter are configured for reflecting light of different colors or polarizations, so as to combine light of different polarization or colors into a single beam.
