Beschreibung
Zusammenfassung:	Disclosed is a metrology device operable to measure a sample with measurement radiation and associated method. The metrology device comprises: an illumination branch operable to propagate measurement radiation to a sample, a detection branch operable to propagate one or more components of scattered radiation, scattered from said sample as a result of illumination of the sample by said measurement radiation; and a dispersive arrangement in either of said illumination branch or said detection branch. The dispersive arrangement is arranged to maintain one or more components of said scattered radiation at substantially a same respective location in a detection pupil plane over a range of wavelength values for said measurement radiation.
