1. Transmission spectrometer comprising a sensor to which, through at least one optical waveguide for emitted radiation, the radiation of at least one radiation source can be introduced, in order to direct it on and/or in an object to be investigated, and with an optical waveguide for detected radiation spaced from the sensor, through which radiation, which was scattered by, transmitted by and/or emitted by the object to be investigated can be introduced to a radiation detector connected to an evaluation unit, the transmission spectrometer further comprising a plurality of radiation sources, each having an adjustable radiation intensity, and which have an emission spectrum which is broadband either per radiation source or for all radiation sources together, and each of which is coupled directly to an optical waveguide for emitted radiation, the radiation detector detecting the entire spectrum of the radiation which is entered in the optical waveguide for detected radiation by diffuse and/or directional reflection, transmission, emission and/or fluorescence, and in the evaluation unit, as a function of at least one program which can be selected through an operating unit for the calculation of at least one parameter, at least the intensity of one given wavelength can be processed, and the evaluation unit is in working connection with the radiation sources in such a way that, depending on the selected program, the intensity of the radiation emitted from each radiation source can be adjusted individually, and wavelengths with corresponding intensities, which arrive from the radiation detector to the evaluation unit, can be selected.
