A coupling provides mechanical, light-guiding, and image-guiding connection of an endoscope to a camera module. It is proposed that a first cylindrical stem, in whose interior a proximal end segment of the light guiding system is received, project in the coupling direction from a coupling end of the endoscope. Also projecting from the coupling end in the coupling direction is a second approximately cylindrical stem whose length and diameter are greater than the length and diameter of the first stem, a proximal end segment of the image guiding system being received in the interior of the second stem. The second stem coacts with an interlock arranged on the camera module, for mechanical interlocking of the coupling. The first and second stems extend at a distance next to one another, and the coupling end of the camera module has receptacles, complementary to the two stems, into which the two stems penetrate. In the base, the receptacle into which the second stem enters is optically connected to the image sensing system of the camera module, and the receptacle into which the shorter first stem can be received has a light guide.

A device for &ldquo;in vivo&rdquo; diagnosis by means of a photosensibilisator light-induced reaction or a reaction caused by intrinsic fluorescence in biological tissue, having an illumination system, which is provided with at least one light source having a lamp system which generates incoherent light in a wavelength range of at least 380 to 680 nm, a light delivering unit which directs the light of said illumination system at the therapy and/or to-be-diagnosed tissue area, and an imaging, image-recording and image-transmitting unit which images the light coming from said tissue area in a proximal image plane. The device is distinguished in that the net spectral transmittance in the light delivering unit and in the image-generating unit of the device are selected in such a manner that, on the one hand, practically no light with a wavelength of &lgr; from the range utilized for excitation, which by nature has relatively high intensity, &ldquo;reaches&rdquo; via the image-generating unit of the device into the proximal image plane, whereas light with a wavelength of &lgr; from the range in which fluorescence occurs can reach the proximal image plane only if it comes from the illuminated tissue are and not from the illumination system.
