  • Spectrometer for analysing the spectrum of a light beam
    Patent number: 9638635
    Abstract: A spectrometer (100) for analyzing the spectrum of an upstream light beam (1), includes an entrance slit (101) and collimating elements (110) suitable for generating, from the upstream light beam, a collimated light beam (10), characterized in that it also includes: a polarization-dependent diffraction grating (120) suitable for diffracting, at each wavelength (11, 12) of the spectrum of the upstream light beam, the collimated light beam into a first diffracted light beam (11, 12) and a second diffracted light beam (21, 22); optical recombining elements (130) including a planar optical reflecting surface (130) perpendicular to the grating and suitable for deviating at least the second diffracted light beam; and focussing elements (140) suitable for focussing, at each wavelength, the first diffracted light beam and the second diffracted light beam onto one and the same focussing area (141).
