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 and receives light from the illumination source reflected off the sample also via the detection fiber bundle for detecting the presence of the sample.

Abstract: A LIBS analyzer and method includes a laser configured to produce a plasma on a sample at a focal point on the sample and a spectrometer responsive to radiation emitted from the plasma and configured to produce an output spectrum. A detector is positioned to detect low intensity pre-firing radiation produced by the laser and reflected off the sample from the focal point. The intensity of the low intensity pre-firing radiation is compared to a predetermined minimum and the laser pump sequence is halted if the intensity of the low intensity pre-firing radiation is less than the predetermined minimum.

Abstract: An analysis (e.g., LIBS) system includes a source of radiation, an optical emission path for the radiation from the source of radiation to a sample, and an optical detection path for photons emitted by the sample. A detector fiber bundle transmits photons to the spectrometer subsystem. At least one fiber of the fiber bundle is connected to an illumination source (e.g., an LED) for directing light via at least a portion of the detection path in a reverse direction to the sample for aligning, sample presence detection, localizing, and/or focusing based on analysis of the resulting illumination spot on the sample.

Abstract: A LIBS analyzer, preferably handheld, includes a laser configured to produce a plasma on a sample and a spectrometer responsive to radiation emitted from the plasma and configured to produce a spectrum. A controller subsystem is configured to control energizing the laser and to analyze the resulting spectrum from each laser pulse to determine if the laser is aimed at a sample. If the analyzed spectrum reveals the laser is not aimed at the sample, the controller subsystem halts the laser puke sequence.

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.
