  "id": "MLC-T-CHM-011132",
  "term": "Spectral photon exitance",
  "field": "Chemistry",
  "definition": "The number of photons emitted from a surface per unit area, per unit time, per unit wavelength interval. This quantity describes the spectral distribution of photon emission from a source. It is commonly expressed in units of photons per square meter per second per nanometer (photons m^-2 s^-1 nm^-1).",
