Glan-Thompson Polarizing Prisms

Glan-Thompson Polarizing Prisms


The prisms are produced from calcite of selected quality which is practically striae- and bubble-free. This grants an extraordinary high extinction ratio over a broad spectral range. The polarizers consist of two prisms joined by optical cement. The ordinary polarized beam experiences total internal reflection and the interface to the cement layer. The side surfaces are coated with black varnish to absorb the reflected o beam.

The prisms are available in a mounted and an unmounted version. The transmitted polarization of our prisms is oriented at 45° with respect to the edges which is of particular importance when integrating unmounted prisms.

The polarizers are not antireflection coated by default.

Versions

The Glan-Thompson prisms are available in four versions. The short version is suited for most applications. It provides a high extinction ratio, high transmission and low wavefront distortion in the visible and infrared spectral range.

The simple version has the same geometrical shape as the short version. By reducing the specifications for the usable spectral range, the extinction ratio and the wavefront distortion we can achieve a very competitive price. Nevertheless, these prisms are high quality polarizers with specifications exceeding those of alternative models. For the long version the crystals are cut at a larger angle.

For the long version the crystals are cut at a larger angle. By this the prisms maintain their polarizing properties even at higher angles of incidence. Therefore, the long version is particularly suited for applications involving strongly divergent or convergent light. The other properties are identical to those of the short version.

BeFor the UV version we select calcite with the highest available UV transmission. The prisms are joined with a UV transparent cement. By this means the prisms become suited for the ultraviolet spectral range starting above 250 nm.
