Summary:Scanning fluorescence microscopes with an observation beam path from a measurement volume to an image plane. A beam combiner is provided for coupling an illumination system and a diaphragm arranged in the image plane for slow composition of the image because of the sequential scanning and subject the sample to loading as a result of inefficient use of the excitation light. The microscope simultaneously detects fluorescence from different focal planes in each case quasi-confocally. The observation beam path between the beam combiner and the image plane has a first diffractive optics for splitting light beams into beam bundles along different orders of diffraction, imparting to the light beams a spherical phase that is different from the other orders of diffraction. A second diffractive optics is provided for the compensation of chromatic aberrations of the split beam bundles, and a collecting optics is provided for focusing split beam bundles into the image plane.
