  "id": "MLC-T-CHM-008895",
  "term": "Photon counting",
  "field": "Chemistry",
  "definition": "A highly sensitive detection technique used to measure very low light intensities by individually detecting and counting photons. This method employs detectors such as photomultiplier tubes or avalanche photodiodes, which produce a discrete electrical pulse for each incident photon. It is widely used in fluorescence spectroscopy and microscopy.",
