Glan Thompson Polarizing Beamsplitter Cubes

Optics >>> Polarizer >>> 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.
