Polarizing Beamsplitter coating are designed to split light by polarization state rather than by wavelength or intensity. Polarizing Beamsplitters are often used in semiconductor or photonics instrumentation to transmit p-polarized light while reflecting s-polarized light. Optical isolators use polarizing beamsplitters to eliminate feedback-induced damage.  Polarizing Beamsplitters are typically designed for 0° or 45° angle of incidence with a 90° separation of the beams. We offer Polarizing Beamsplitters in a range of including plate and cube.
