Abstract: A handheld LIBS spectrometer includes an optics stage movably mounted to a housing and including a laser focusing lens and a detection lens. One or more motors advance and retract the optics stage, move the optics stage left and right, and/or move the optics stage up and down. A laser source in the housing is oriented to direct a laser beam to the laser focusing lens. A spectrometer subsystem in the housing is configured to receive electromagnetic radiation from the detection lens and to provide an output. A controller subsystem is responsive to the output of the spectrometer subsystem and is configured to control the laser source and motors. In this way, auto-calibration, auto-clean, and auto-focus, and/or moving spot functionality is possible.

Abstract: A spectrometer system and method including a laser source for directing a laser beam to a sample producing plasma radiation on the sample. At least one fiber of a fiber bundle is connected to an illumination source for directing light to the sample. A spectrometer subsystem receives plasma radiation from the sample via the detection fiber bundle. A camera receives light from the illumination source reflected off the sample for detecting the presence of the sample.

Abstract: A combined handheld XRF and LIBS system and method includes an XRF subsystem with an X-ray source operated at a fixed medium voltage and configured to deliver X-rays to a sample without passing through a mechanized filter and a detector for detecting fluoresced radiation from the sample. The LIBS subsystem includes a low power laser source for delivering a laser beam to the sample and a narrow wavelength range spectrometer subsystem for analyzing optical emissions from the sample. The X-ray source is operated at the fixed medium voltage to analyze the sample for a first group of elements, namely, transition and/or heavy metals. The low power laser source is operated to analyze the sample for a second group of elements the XRF subsystem cannot reliably detect, namely, C, Be, Li, Na, and/or B, and to analyze the sample for a third group of elements the XRF subsystem cannot reliably detect at the fixed voltage, namely, Al, Si, and/or Mg, or where the XRF subsystem would require higher tube voltage, namely Cd, Ag, In, Sn, Sb, and/or Ba; and/or rare earth elements.
