Glan Thompson Polarizer

Glan Thompson Polarisers  has a wavelength range from 350 nm to 2300 nm. This NIR and UV-VIS polarizer is recommended for low-to-medium power applications (up to 2W cw) requiring a large field of view and the highest degree of polarization purity. The Glan-Thompson Polarizer is made from two calcite elements cemented together to form a prism. This configuration reduces its power-handling capability but results in an increased field of view. The angular field of view of this UV-VIS polarizer is asymmetrical about the mechanical axis and varies as a function of wavelength as shown below. The rejected (ordinary) beam is absorbed by the prism housing.
This polarizer is ideal for removing interference fringes from transmission spectra recorded at Brewster's angle and for obtaining optimum sensitivity for specular reflection spectroscopy measurements.
