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.
