Polarizing Beam Splitter Cubes ( PBS Cube )

Polarizing Beam Splitter Cubes (PBS Cube) are constructed by cemented two precision high tolerance right angle optical prisms; the hypotenuse of one prism is coated with polarization dielectric coating. It randomly polarized beams into two orthogonal, linearly, polarized components. S-polarized light is reflected at a 90 degree angle while P-polarized light is transmitted. The PBS cube can be used as a polarizer, beam splitter or beam combiners in Polarizing Optic field. The output beam which is parallel to input beam is called p-polarized beam while the orthogonal output beam is defined as s-polarized beam.

PBS Cube Polarizer with extinction ratio from 300:1 to 1000:1 are available, Polarization Beamsplitters or Beam Combiners from Coupletech have a very wide range of coatings: i.e. Narrow Band: 488nm, 532nm, 632.8nm, 650nm, 808nm, 850nm, 980nm, 1064nm, 1310nm, 1550nm and Broadband: 450-650nm, 650-850nm, 900-1200nm, 1200-1550nm, 1500-1610nm. The size of Beamsplitter from Coupletech is 5 x 5 x 5mm3, 9 x 9 x 9mm3, 10 x 10 x 10mm3, 12.7 x 12.7 x 12.7mm3, 15 x 15 x 15mm3, 20 x 20 x 20mm3 and 25.4 x 25.4 x 25.4mm3, Other size can be customized. Polarizing Beam Splitter is frequently used as Polarization Optics materials and Optical elements.
