Abstract

A method of and a device for the endoscopic fluorescence diagnosis of tissue, wherein the tissue is exposed to stimulating light via an endoscope for stimulation of fluorescence, which stimulating light is suitable, on account of its spectral distribution, to stimulate at least two different fluorescence modes in the tissue without filter switching in the stimulation beam path, and wherein the fluorescence light of the different fluorescence modes can be selectively observed.
