GLAN THOMPSON CALCITE POLARIZER
₹30,000.00
Glan-Thompson polarizers consist of two cemented prisms made from the highest optical grade calcite. Unpolarized light enters the polarizer, then is split at the intersection of the two crystals allowing s-polarized (e-ray) light to continue and p-polarized light (o-ray) to be reflected.

Thin film polarizers are optical components designed to selectively transmit light of a specific polarization while reflecting light with the orthogonal polarization. This ability to control the polarization state of light makes thin film polarizers invaluable in laser systems where precise manipulation of laser beams is essential.
A calcite Beam Displacer splits the input unpolarized beam of light into two orthogonally polarized components which exit parallel to each other. The ordinary polarization transmits straight through while the extraordinary transmits through the crystal making approximately 6 degree angle with the straight through beam and emerges parallel to it. The beam displacement varies slightly with wavelength.
A Wollaston prism is an optical device, invented by William Hyde Wollaston, that manipulates polarized light. It separates light into two separate linearly polarized outgoing beams with orthogonal polarization. The two beams will be polarized according to the optical axis of the two right angle prisms of Crystal Calcite.
Other custom separation angle can be designed upon your request.
Rochon prisms are made of two birefringent, which are cemented together. The ordinary ray remains on the same optical axis as the input beam, while the extraordinary ray deviates by an angle, which depends on the wavelength of the light and the material of the prism.

Glan-Taylor Polarizers produce extremely pure linear polarization with an extinction ratio greater than 100,000:1 and are meant for use with laser beams in the 350 nm – 2.3 μm wavelength range. A significant amount of reflected light escapes the polarizers through the side port, including all of the ordinary ray and some of the extraordinary ray. As such, the escape beam is not fully polarized, and only the transmitted extraordinary ray should be used for applications that require a high-quality, polarized beam.
