Polarization Beamsplitter

Ploarization Beamsplitter (PBS) is of high precision T/R ratio, that is her most impornat and attractive feature.It is easy to mount/ align and operation. OP-Unite can supply both narrowband and broadband wavelength polarization beamsplitter cube. They are widely used in projection optics systems, measurement or imaging and optical display systems.
