Abstract
A measuring device measures singlet oxygen luminescence which is excited by one or more photosensitizers. The measuring device contains a photosensitive detector, an excitation source, and a control and evaluating unit that is coupled to the photosensitive detector and the excitation source. The excitation source is configured to radiate excitation light into a measurement volume from a plurality of emission positions in order to excite the photosensitizer or photosensitizers. The excitation source preferably contains light-emitting diodes as lighting devices, the light of which is used directly as an excitation light in order to excite the photosensitizers.
