Polarizing Beamsplitters are Beamsplitters 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, depending on the configuration.

Edmund Optics offers a wide variety of Polarizing Beamsplitters in a range of configurations including plate, cube, or lateral displacement. Plate Beamsplitters are available in many sizes for optimized performance when used with ultraviolet, visible, or infrared wavelengths. Cube Beamsplitters are ideal for applications requiring durability or simplified mounting or system integration. Lateral Displacement Beamsplitters are designed to split the incident beam into two displaced parallel beams. Polarizing Beamsplitters are available that have been designed for common laser wavelengths or wavelength ranges.
