Lithographic apparatus and device manufacturing method
A sensor is used to detect luminescent radiation that is radiated from a reflector as a result of state changes induced by a beam of radiation being incident on an area of the reflector. The intensity of the luminescent radiation at particular wavelengths can be used to determine the intensity of th...
