    • The invention relates to an apparatus for in vivo diagnosis using a reaction in biological tissue that is induced by light from a photosensitizer or by intrinsic fluorescence and comprising an illumination system with at least one light source with a lamp system (6) that generates light at a wavelength ranging from 380 to 680 nm, a light-guiding unit (2, 5, 21) that directs the light from the illumination system onto the tissue region (7) for diagnosis or treatment, and an image-forming, image-detecting and image-transmitting unit (31, 32, 4, 8) that depicts the incoming light from the tissue region (7) in a proximal focal plane, where the spectral internal transmittance Tl( lambda ) of the light-guiding unit is adjusted to the fluorescence excitation spectrum of the photosensitizer or of the tissue and the spectral internal transmittance Tb( lambda ) of the imaging unit is adjusted to the fluorescence spectrum of the photosensitizer or the tissue, and where the internal transmittance of the entire system of light-guiding and imaging units has a spectral internal transmittance of more than 5 % only within a range of wavelength of at most 50 nm and otherwise is less than 5 % in the above-mentioned wavelength range.
