摘要：
An endoscopic, exoscopic or microscopic apparatus for fluorescence diagnosis comprises a light source designed to emit light in a first spectral range and light in a second spectral range in a fluorescence mode The second spectral range is at least partly separate from the first spectral range. The light source has at least one first semiconductor illuminant which emits the light in the first spectral range in the fluorescence mode. The light source has at least one second semiconductor illuminant which emits the light in the second spectral range in the fluorescence mode. The apparatus comprises an open-loop or closed-loop control device, which keeps constant a preset ratio of a first intensity of the light in the first spectral range and a second intensity of the light in the second spectral range.
