A polarizing beam splitter (16), dividing the incident beam (11) into its S- and P-polarized components (S, P), and a half-wave plate (17), rotating polarization by 90 deg , are used to ensure that the light passes through the rotatable interference filter (14) of the analyzer in one polarization state only.
