Polarization Beamsplitter Cube
|
|
|
|
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.
TEMTO can supply both narrow and broadband wavelength polarization beamsplitter cube. They are widely used in projection optics systems, measurement or imaging and optical display systems. |
