Beam Combiner/ Splitter

Polarization Beam Splitter/Combiner

Polarization beam splitter can be used as beam splitters or beam combiners. The output beam which are parallel to input beam is called p-polarized beam while the orthogonal output beam is defined as s-polarized beam. The polarization beam splitter plates are available for red, blue, and green lasers, you can choose the one you require, we will offer our customer the solution for the beam combining.
