Narrowband polarising beam splitter cubes are the most common solution for polarisation separation. They offer low cost and high extinction ratios, optimised for a single wavelength and suitable for relatively high-power levels. Higher power handling options are also available, which are optically contacted, unlike the lower-cost cemented cubes. High-power cubes offer an LIDT similar to that of a thin film polariser.
Finally, broadband beam splitter cubes are available for separating s-pol and p-pol for larger bandwidths. A number of standard wavelength ranges are available from 440-1600nm. All beam splitter cubes are offered from 10.0-50.8mm, with custom sizing possible upon request.
