Summary:The development of a unique spectrometer based on an array of Geiger photodiodes has been shown to enhance the performance of laser-induced breakdown spectroscopy (LIBS) instrumentation. These compact, silicon-based detectors eliminate the need for postamplification electronics, allow for the detection of single photons at room temperature, and do not require complex gating-timing circuitry. The detectors have dark-count rates of <500 Hz at room temperature and a good response from the UV to the near IR. Their high sensitivity makes them candidates for standoff analysis as part of a LIBS spectrum analyzer.
