Optical Polarizing Beam Splitter is a device designed to divide or split an incident unpolarized beam into a reflected S- polarized and a P- polarized beam. These S and P polarizing beam splitters refer to the electric field in which the wave is oscillating. The S polarization can simply be explained as the plane of polarization perpendicular to the page while the p polarization is the plane polarization parallel to the page. Instead of these beam splitters to split light beams by wavelength or by intensity, it functions in a way that it polarizes light beams by polarization state. They are mostly employed in photonics instruments like laser diodes, light-emitting diodes, solar and photovoltaic calls, display, and optical Amplifiers. Optical Polarizing Beam splitters are also used in semiconductors to transmit p-polarized light and reflect s-polarized light. Polarizing Beamsplitters are generally designed for 0° or 45° viewpoint of incidence with a 90° separation of the beams, relying on the configuration. At Alpine Research Optics we offer a wild range of Optical Polarizing Beam Splitters. A polarizing Beam splitter can come in a cube or plate optical Polarizing Beam Splitter.

 

Features Of Optical Polarizing Beam Splitter

They come in different dimensions like 10.0×10.0×10.0mm, 25.0×25.0×25.0mm, 5.0×5.0×5.0mm, etc with wavelength ranging from 345.0 – 1100 nm, and varies in shapes from cube too many large optical mirrors to prison and wire gride. In terms of polarization, it can either be a linear polarizer beam splitter or a non-polarization beam splitter. One would be confused about what is linearly polarized light to circularly polarized light, when light moves in the form of a plane wave in space, it is said to be linearly polarized but when two plane waves of different amplitude are related in phase by 90° or relative phase is other than 90°, is said to be elliptically polarized.

 

Cube Optical Polarizing Beam Splitter

In terms of forms, the cube polarizing Beamsplitters include the laser line polarizing cube beam splitters which are designed for common diode, gas, and solid-state lasers. It also includes laser line high energy polarizing cube beam splitters which are optically contacted designed to increase damage threshold, eliminate cement fluorescence. The laser line high energy polarizing cube beam splitters have 96% of its transmission as a p-polarized beam. The wire grid polarizing cube beam splitters have a high contrast over large angles of incidence, poor color shift over the same angles, and are ideal for uncollimated light sources. The broadband polarizing cube beam splitters, have a visible and NIR coating, a 500:1 ratio Extinction with an AR coating of less than 0.5% reflection per surface.

 

Plate Optical Polarizing Beam Splitter

Broadband plate polarizing beam splitters are unique in their way as it comes with a wire grid technology, it is ideal for hot temperature, reflects S-polarized light, and Transmit P-polarized light.

 

Lateral Displacement beam splitter

Apart from the plate Optical Polarizing Beam Splitter and the cube optical Polarizing Beam Splitter we also have the lateral displacement beam splitter which has a visible and NIR coating option, a simplified benchtop layout, and a split incident beam into two different parallel beams.
