Abstract: Disclosed is a spectroscopy device, including an analysis zone for receiving a sample; at least one light-emitting diode arranged to emit a light beam towards the analysis zone, having a luminous intensity spectral profile in a working wavelength interval; unit for varying with time the luminous intensity spectral profile emitted by the diode in the working wavelength interval of the diode; a detector, arranged to receive, during a variation with time of the luminous intensity spectral profile emitted by the diode, the light beam emitted by the diode and having crossed the analysis zone, and supplying a detection signal of the light beam emitted by the diode and received by the detector, in the form of a signal which depends on at least one characteristic representative of the luminous intensity spectral profile of the light-emitting diode. Application to derivative spectroscopy.
