Patent ID: 7982189

Claim:
A spectrometer comprising: a lighting device configured to generate a light beam covering a wavelength band, a probe configured so that the light beam coming from the lighting device interacts with a fluid to be analyzed, and a spectrum analyzing device configured to receive the light beam after it has interacted with the fluid to be analyzed, and to provide measurements depending on a quality of light received for various ranges of wavelengths, the spectrum analyzing device comprising a first light guide coupled to the probe and receiving the light beam after it has interacted with the fluid to be analyzed and diffusing it to a first set of light-sensitive cells through a first optical filtering device arranged to send each of the light-sensitive cells of at least one part of the set of light-sensitive cells, a part of the light beam covering a respective range of wavelengths included in the wavelength band, the first light guide having the shape of a plate made of a transparent material, receiving the light beam coming from the fluid to be analyzed by an edge of the plate and diffusing it by spreading it to an opposite edge of the plate opposite which the first filtering device and the first set of light-sensitive cells are placed.
