Abstract

The present invention provides a device for obtaining data from a sample. This device comprises an external equipment with a laser source, a Raman spectrometer and an external LIBS spectrometer and a handheld probe. An excitation barrel (1) is configured to produce a collimated laser beam, the first folding mirror (2) is arranged to reflect the collimated laser beam and the first dichroic (3) is configured to project the reflected collimated laser beam into a first direction. A LIBS excitation source (6) is configured to produce a pulsed laser beam, a beam expander (7) is configured to produce an expanded laser beam with the same collimation status as the collimated laser beam, the second folding mirror (8) is arranged to reflect the expanded laser beam and the second dichroic (9) is configured to project the reflected expanded laser beam into the first direction. A focuser (4) is arranged in the first direction and is arranged to receive the reflected collimated laser light and the reflected expanded laser beam and focus them on a focusing point. The device further comprises a Raman collection barrel (5) and a LIBS collection barrel (10). Finally, an optical component (12) is configured to reflect part of the sample light coming from the focuser (4), a diaphragm (13) is configured to receive the light reflected by the optical component (12) and a camera system is configured to receive the light which passes through the diaphragm (13).
