The transmission loss is minimal, and a high extinction ratio below 5×10-5 is obtained. The Calcite type that can be used in the visible to the infrared region, and α-BBO crystal type usable in the ultraviolet region are available. The polarizer provides a very short prism length.
◦The two prisms are mounted with a small gap (air-gap) to eliminate the adhesive and reduce laser damage. ◦A single-layer anti-reflection coating has been applied on the surface of the polarizing prism to provide high transmittance.
Glan laser prism for high-power laser (GLPB / GLP) and Wollaston prism (WPPB / WPPC) are also available.
WEB Reference Catalog Code/W3451, WEB Reference Catalog Code/W3453
If you need uncoated Glan Thompson prism or anti-reflection coating with specific reflectance, please contact our Sales Division with your request.
Remark
-
Attention
A change in the incident angle may also changes the extinction ratio of the linearly polarized transmitted light.
Light not transmitted through the Gran Taylor prism is absorbed and scattered in all side faces of the prism. In the high-precision measurement system, it is necessary to use pinhole to block light scattered in the side face of the prism.
Because of natural calcite crystals, there are individual differences, and variations in quality.
