Polarizer	Material	Illustration	Properties & Application
Glan-Taylor Prism	α-BBO(190-3500) Calcite(350-2300) YVO4(450-5000)		Air-spaced. Cutting angle close to Brewster ±s Angle. The extraordinary ray passes through straightly with little deviation. Sealed mount without escape windows. Suits for low to medium power application where the rejected beam is not required.
Glan- Laser Prism	α-BBO(190-3500) Calcite(350-2300)		Better than Glan Taylor polarizer. Mounted with escape windows. Suits for high power application.
Glan-Thompson Prism	Calcite(350-2300)		Cemented. Suits for low power application. Special design for ratio of L/A (length/aperture) guarantees wide acceptance angle.
Wollastom Prism	Calcite(350-2300)		Cemented. Both ordinary and extraordinary beams are deviated. Suits for low power application and where large deviation is required.
Rochon Prism	α-BBO		Broad wavelength range. High UV transmission.n High extinction ratio. Large field angle.
