The polarization state of the BESSY UE56/1-PGM beamline radiation in the broad wavelength range of 12.7–15.5 nm was measured using a molybdenum/silicon transmission phase retarder and a reflection analyzer with aperiodic multilayer interference structures, which can broaden the spectral response of these optical elements. The characteristics of the circular polarized undulator radiation, as well as the polarization properties of the two polarizing elements, were determined by a complete polarization analysis. Furthermore, the polarization of the radiation as a function of the undulator shift setting was also measured at the wavelength of 13.1 nm by use of the broadband phase retarder-analyzer pair.
