Glan-Thompson Prism

Glan-Thompson Prism
A Glan-Thompson Prism is used for obtaining linear-polarized light and consists of two spar prisms glued together. The use of glue causes the increase of transmittance in comparison to the Glan-Taylor prism because of decrease of Fresnel losses on hypotenuse facets but lessens working spectral range in the ultraviolet region. An extraordinary ray is a working one, and a reflected ordinary ray is absorbed by lateral faces.
