Polarizers


A polarizer is an important optical component that is widely used in optics to produce a state of linear polarization. Casix provides polarizers with three materials, α-BBO, calcite and YVO4, making them suitable for the widest spectrum and high polarization purity application.

  Properties and Applications
Glan Taylor Polarizer
α-BBO (200-3500)
Calcite (350-2300)
YVO4 (450-5000)
polarizer-1

-Air-spaced
-Cutting angle close to Brewsterundefineds angle
-The extraordinary ray passes through with little deviation
-Sealed mount without escape windows is suitable for low to medium power applications where the rejected beam is not required

Glan Laser Polarizerα-BBO (200-3500)
Calcite (350-2300)
polarizer-2

-Cutting angle close to Brewsterundefineds angle
-Mounted with escape windows, therefore it is suitable for high power applications

Glan Thompson PolarizerCalcite (350-2300)polarizer-3

-Cemented
-Suitable for low power applications
-Special design for the ration of L/A (length/aperture) guarantees the wide acceptance angle

Wollaston PolarizerCalcite (350-2300)polarizer-4

-Cemented
-Both ordinary and extraordinary beams are deviated
-Suitable for low power applications and where a large deviation is required

Rochon Polarizerα-BBO (190-3500)polarizer-5

-Made by α-BBO material guaranteeing a wide transmission range, especially suited for UV applications
-Split the ordinary and extraordinary ray, but only extraordinary beam is deviated
-Wide wavelength range
