Polarizing Beamsplitter Cubes
With a special broadband beamsplitter coating on the hypotenuse and a corresponding AR coating on the four optical outer surfaces, these cubes are suited for universal applications and as part of a basic laboratory equipment. They separate the S and P polarization components by reflecting the S component at the beamsplitter coating, while allowing the P component to pass with an extinction ratio of Tp:Ts > 1000:1.
