Glan Thompson Polarizing Beamsplitter Cubes, FOCtek
These Glan Thompson polarizers have been arranged to permit ther output of the s-polarized beam at 45 deg 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.
