Polarizer | Material | Illustration | Properties & Application |
Glan-Taylor | 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 | aα-BBO(190-3500) Calcite(350-2300) |
| Better than Glan Taylor polarizer. Mounted with escape windows. Suits for high power application. |
Glan-Thompson | Calcite(350-2300) |
| Cemented. Suits for low power application. Special design for ratio of L/A (length/aperture) guarantees wide acceptance angle. |
Wollastom | Calcite(350-2300) |
| Cemented. Both ordinary and extraordinary beams are deviated. Suits for low power application and where large deviation is required. |
Rochon | aα-BBO |
| Broad wavelength range. |
