Glan Thompson Polarizing
Beamsplitter Cubes
|
These Glan Thompson polarizers have been arranged to permit their
output of s-polarized beam at 45 degree from the straight through
p-polarized beam. They provide high polarization purity and high
transmission in the two emerging beams. These are useful if it is required
to utilize both linear polarization states . They are mounted in a
rectangular metal cell and surrounded with an absorbing compound.
