Polarizing Beamsplitter (PBS) Cube
PBS Cube can be used as polarizers, beamsplitters 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.
For all kinds of Polarizing Beamsplitter Cube, the smallest size we can supply is 0.8x0.8x0.8mm.
