High Power Cubes


Especially suited for high laser powers as, due to the optical contacting, no glue is required between the hypotenuses which would otherwise reduce the damage threshold significantly. These cubes 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.
