An apparatus for the spectral diagnosis of substances and/or surfaces includes a radiation source which can be variably adjusted over a predetermined spectral range and whose emitted radiation is focused onto a sample to be examined, wherein a first optical sensor unit detects a radiation component, which is influenced by the sample to be examined, as a useful signal and forwards it to an evaluation and control unit, and to an associated method. The radiation source comprises a light-emitting diode with a predetermined emission wavelength which can be varied between a first emission wavelength and a second emission wavelength by a dynamic change in temperature of the light-emitting diode within the predetermined spectral range, wherein a second optical sensor unit detects a component of the emitted radiation as a reference signal and forwards it to the evaluation and control unit for error compensation purposes.
An apparatus for the spectral diagnosis of substances and/or surfaces comprising a radiation source, which can be tuned in a predetermined spectral range and the emitted radiation of which is substantially focused onto a sample to be examined, said apparatus comprising a first optical sensor unit which:
