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.
