An imaging system for the fluorescence-optical visualization of a two-dimensional or three-dimensional object is provided. The imaging system comprising an illumination unit, which is designed and provided for emitting optical radiation in a predetermined wavelength range in order to illuminate the object and excite a fluorescent substance contained in the object, and a capturing unit, which is designed and provided for capturing an optical signal from the region of the object and for splitting the optical signal into a fluorescence signal having a first wavelength range and a signal of visible light having a second wavelength range. The optical capturing unit has an optoelectronic converter having a plurality of partial regions and serving for converting the fluorescence signal into a first electronic data signal and the signal of visible light into a second electronic data signal.
