ABSTRACT
An efficient mode for scanning confocal dark-field microscopy through a thin gold film is established that takes advantage of the intermediate excitation of surface plasmons both in the excitation and in the emission process. This concept is verified by experimental investigation of the effective point-spread function, the intensity distribution of the scattered radiation and by comparison with a classical dark-field geometry. The wavelength-dependence of both the signal strength and the point-spread function are discussed.
