Patent ID: 8264681

Claim:
A spectrometer comprising: a laser source configurable to produce a lased light of a single wavelength directable towards a target substance, the laser source having sufficient power to selectively cause a portion of the target to emit Raman scattering and ablate a portion of the target substance to produce a plasma plume by illumination of said target substance with lased light of the same single wavelength; a separate remote light collector optically configurable to collect light emitted from the portion of the target emitting Raman scattering and from the portion of the target producing the plasma plume; a filter optically coupled to the remote light collector to remove reflected light and Rayleigh-scattered light; a spectroscope optically coupled to the filter and configured to separate the collected and filtered light into a frequency spectrum comprising a Raman spectrum and a laser-induced breakdown spectrum; and an electronic light sensor to record the frequency spectrum.
