Patent ID: 7161673

Claim:
A spectrometer comprising a dispersive element of a light beam formed of a set of spectral components, the dispersive element generating spatial dispersion of the spectral components in the form of a dispersion spectrum spatially spread, at least two photon detectors, each comprising at least one detection element being provided at one point of said dispersion spectrum, wherein a matrix optical electromechanical device is provided between the dispersive element and the at least two photon detectors in the dispersion spectrum, said matrix optical electromechanical device being formed of a matrix of optical elements, each of the optical elements being able to send back a portion of the dispersion spectrum according to at least two directions in relation to a control signal, in order to enable the selection of at least one sub-assembly of the spectrum for each of said detection element, and wherein at least one of the at least two photon detectors is a photomultiplier comprising one detection element and at least one of the at least two photon detectors is a one- or two-dimensional matrix device comprising at least one detection element.
