摘要： A spectrometer (20) has a source of illumination radiation (21) having a plurality of spectral wavelengths, a bandpass filter (14), a dispersive beamsplitter (28), an illumination radiation rejection filter (34), and a spectrograph (32) each tunable in correspondences to a selected one of the plurality of spectral wavelengths of the source of illumination radiation. Any one of the tunable elements can comprise a holographic volume dispersion distraction grating and a mirror, both having fixed orientation displacement with respect to each other and being rotable for tuning around an avis corresponding to the interaction of the two planes coincident with the surfaces of said mirror and said grating.
