· A polarizer which increases the laser durability when used with high-output lasers or high-energy pulse lasers.
· There is little transmission loss, and a high extinction ratio of 5 x 10^-5 or less can be obtained.
· Calcite type used from the visible region to the infrared region and α-BBO crystal type used in the ultraviolet region are also available.
· The two prisms are joined with only a small gap (air gap).
· Therefore, absorption due to adhesive and degradation of laser strength will not occur.
· The Glan laser prism is contained in a metal frame.
· Polarized components that didn't permeate the prism pass through the port (hole) in the metallic frame to the exterior.
· Because there are two ports, the incident and emission directions can be switched for use.
· A single layer of antireflection film coating has been applied to the surface of the Glan laser prism, achieving high transmittance.
· Glan-Thompson prism GTPB/GTPC and Wollaston prism WPPB/WPPC with wide permissible angles are also available.
· If a permissible angle is required, check the specification.
· * The extinction ratio of linearly polarized transmittance light will also change if the incident angle is changed.
· * Calcite is a natural crystal, and as such each one has its own individual characteristics with variations in quality.
