Glan Thompson Prism / GTPB-15-32.5SN

This is a special polarizer with minimal transmission loss, and a high extinction ratio below 5×10-5 is obtained. It is used in high-precision polarization experiments. The Calcite can be used in the visible to the infrared region, and α-BBO crystal type usable in the ultraviolet region are available.
