A spectrometer has a source of illumination radiation having a plurality of spectral wavelengths, a bandpass filter, a dispersive beamsplitter disposed in an optical path of said source of illumination radiation, an illumination radiation rejection filter, and a spectrograph disposed in a path of radiation from a sample illuminated by illumination radiation from said source of illumination radiation. The dispersive beamsplitter, the bandpass filter, the illumination radiation rejection filter and spectrograph are tunable in correspondence to a selected one of the plurality of spectral wavelengths of the source of illumination radiation. The dispersive beamsplitter directs the selected one of the plurality of spectral wavelengths of illumination radiation to a sample and directs elastically scattered and reflected radiation from the sample out of a measurement beam of light emanating from the sample. The inelastically scattered light passes through the dispersive beamsplitter essentially unaffected and is directed to the illumination radiation rejection filter and the spectrograph.
