Polarizers

Polarizer is an important optical component that is widely used in polarizing optics to produce the state of linear polarization. CASIX provide following polarizers with three materials,a-BBO, Calcite and YVO4 to suit for widest spectrum and high polarization purity application.

Polarizer Material Illustration Properties and Application
Glan-Taylor
Polarizer 		a - BBO
(190-3500) Calcite
(350-2300) YVO4

  • Air-spaced
  • Cutting angle close to Brewster's Angle.
  • The extraordinary ray passes through with little deviation.
  • Sealed mount without escape windows is suitable for low to medium power application where the rejected beam is not required.
Glan-Laser
Polarizer 		a - BBO
(190-3500) Calcite
(350-2300) 		spolarizer02.JPG (9010 bytes)
  • Cutting angle close to Brewster's angle
  • Mounted with escape windows.
    Therefor, it is suitable for high power applications.
Glan-Thompson
Polarizer 		Calcite
(350-2300) 		spolarizer03.JPG (5406 bytes)
  • Cemented.

  • Suitable for low power applications.
  • Special design for the ratio of L/A (length/aperture) guarantees the wide acceptance angle.
Wollastom
Polarizer 		Calcite
(350-2300) 		spolarizer04.JPG (7407 bytes)
  • Cemented.
  • Both ordinary and extraordinary beams are deviated.
  • Suitabel for low power application and where the large deviations is required.
Rochon
Polarizer 		a - BBO
(190-3500) 		spolarizer05.JPG (6993 bytes)
  • Made by a-BBO material guaranteeing a wide transmission range, especially, suitable for UV applications.
  • Split the ordinary and extraordinary ray, but only extraordinary beam is deviated.
  • Wide wavelength range
