Abstract: An spectrometer including Raman and LIBS spectroscopy capabilities is disclosed. The spectrometer includes a laser source configurable to produce a lased light directable towards a target substance, the laser source having a single wavelength and having sufficient power to cause a portion of the target to emit Raman scattering and sufficient to ablate a portion of the target substance to produce a plasma plume. A separate remote light collector is 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 is optically coupled to the remote light collector to remove reflected light and Rayleigh-scattered light, and a spectroscope is 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. Finally, an electronic light sensor is used to record the frequency spectrum.
