Polarizers

Polarizers


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


Polarizer Material ILLUSTRATION PROPERTIES AND APPLICATIONS
Glan Taylor Polarizer α-BBO
Calcite
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 applications where the rejected beam is not required
Glan Laser Polarizer α-BBO
Calcite
YVO4
Cutting angle close to Brewster's angle
Mounted with escape windows, therefore it is suitable for high power applications
Glan Thompson Polarizer α-BBO
Calcite
Cemented
Suitable for low power applications
Special design for the ration of L/A (length/aperture) guarantees the wide acceptance angle
Wollaston Polarizer α-BBO
MgF2
YVO4
Calcite
Quartz
Cemented
Both ordinary and extraordinary beams are deviated
Suitable for low power applications and where a large deviation is required
Rochon Polarizer α-BBO
MgF2
YVO4
Quartz
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
