Properties
and Application
|
|
Polarization
Beamsplitter
|
|
Material:
BK7 glass
Special polarizing coating for
Single wavelength.
Broadband wavelength.
|
|
Glan-Taylor
Polarizer
|
|
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
|
|
Cutting angle
close to Brewster's angle
Mounted with escape windows.
Therefore, it is suitable for high power applications.
|
|
Glan-Thompson
Polarizer
|
|
Cemented.
Suitable for low power applications.
Special design for the ratio of L/A (length/aperture)
guarantees the wide acceptance angle.
|
|
Wollastom
Polarizer
|
|
Cemented.
Both ordinary and extraordinary beams are deviated.
Suitable for low power application and where the large
deviations are required.
|
|
Rochon
Polarizer
|
|
Split the
ordinary and extraordinary ray, but only extraordinary
beam is deviated.
Wide wavelength range
