Abstract:
A spectrometer including: a spectral dispersion mechanism of an initial light beam; and a photodetector. The spectral dispersion mechanism includes at least three reflective diffraction gratings parallel to consecutive sides of a convex polygon, arranged such that a portion of the initial light beam is diffracted once by each diffraction grating in turn and is diffracted at least a second time by at least one of the diffraction gratings.
