Keysight NPBS graph

Here is a typical graph for our broadband non-polarizing beam splitters. Measurements were done at the reflectance and transmittance outputs. Important for a non-polarizing splitter is that the ration between the S- and P-polarizations remains as close as possible to the ratio of the S- and P-polarizations of the input beam.

The non-polarizing beam splitter is a plan-parallel plate which has a splitter coating on the entrance surface. Note: the exit surface for the transmitted beam has an anti-reflection coating to prevent (partial) reflection of the transmitted beam.
