Glan Thompson Polariser, Calcite, 350-2200nm

Manufacturer's part number :


Manufacturer Altechna


Description :

A Glan Thompson prism is a birefringent polarizing element which consists of two calcite prisms cemented together. Because of the cement it has higher transmission than a Glan Taylor type Polariser due to the reduced reflection losses at the hypotenuse interface but limited useful UV spectral range. The transmitted beam of extraordinary polarization is used. Side faces are black painted to absorb the rejected beam.
