A fluorescence diagnosis system has a viewing system at least one light source and a camera system. The at least one light source can be operated in three modes, a first generating white light, a second with a first fluorescence excitation light of a first excitation wavelength and a third in which a second fluorescence excitation light of a second excitation wavelength is generated producing a fluorescence image in the NIR range. The camera system is sensitive at least in the visible and the NIR range. The system further comprises an image processing system for converting the fluorescence image in the NIR range into a visible image.

Multifunctional fluorescence diagnosis system

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.

Apparatus for photodynamic diagnosis

An apparatus for producing various laser wavelengths from the same laser medium by means of resonator mirrors. In accordance with the apparatus any desired, given combination of laser wavelengths can be brought to emission simultaneously or at least in very rapid alternation (switching time 1 ms) with the use of standard resonator mirrors linearly arranged outside of a laser medium, with part of at least one of the resonator mirrors being configured so that it serves as resonator limitation for a certain laser wavelength or wavelength group but another part of the at least one of the resonator mirrors constitutes an intracavity element for the respective other wavelength(s) or wavelength group(s).
