BEAMSPLITTER CUBES

TOWER OPTICAL 社製 Beam Splitter Cubes

Polarization Beamsplitter Cubes

These beamsplitters are based upon using two complementary prisms. The output beam, which is parallel to the input beam, is called the p-polarized beam, while the orthogonal output beam is defined as s-polarized.
