Abstract
A fluorescence light scanning microscope () comprises a light source providing excitation light () for exciting a fluorophore in a sample to be imaged for spontaneous emission of fluorescence light, and suppression light () for suppressing spontaneous emission of fluorescence light by the fluorophore on a common optical axis (), the suppression wavelength differing from the excitation wavelength; an objective () focusing both the excitation () and the suppression () light to a focus point; a detector () detecting fluorescence light () spontaneously emitted by the fluorophore; and a chromatic beam shaping device () arranged on the common optical axis (), and including a birefringent chromatic optical element () adapted to shape a polarization distribution of the suppression light () such as to produce an intensity zero at the focus point, and to leave the excitation light such as to produce a maximum at the focus point.
