Polarization Beamsplitter
Ploarization Beamsplitter 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. |
