Polarizing Beamsplitter Cubes
With a broadband beamsplitter coating on the hypotenuse and a corresponding AR coating on the four outer optical surfaces, these cubes are suited for universal applications. They separate the S and P polarizations by reflecting the S component at the beamsplitter coating while transmitting the P component.

High Power Cubes
Especially suited for high laser powers as, due to the optical contacting, no glue is required between the hypotenuses. This results in a significantly improved LIDT.

Non-Polarizing Beamsplitter Cubes
On customer request we produce non-polarizing beamsplitter cubes with an adapted beam splitting ratio from 05:95 to 90:10 for a specified wavelength. The material of the prisms is adjusted to the wavelength and the cubes are either glued or optically contacted for high laser powers. Cubes can be manufactured in sizes from 5 mm to 50 mm.
