Beschreibung
Zusammenfassung:	Disclosed is a metrology apparatus for use in a lithographic manufacturing process. The metrology apparatus comprises a radiation source comprising a drive laser having an output split into a plurality of optical paths, each comprising a respective broadband light generator. The metrology apparatus further comprises illumination optics for illuminating a structure, at least one detection system for detecting scattered radiation, having been scattered by the structure and a processor for determining a parameter of interest of the structure from the scattered radiation.
