  "id": "MLC-T-CHM-003305",
  "term": "Dispersion plane",
  "field": "Chemistry",
  "definition": "The plane that contains the source, the detector, the incident X-ray beam and the specularly reflected beam in X-ray reflectometry. Incidence and reflection angles are measured in this plane, and the sample surface normal lies in it. In a grating or prism spectrometer the analogous plane is the one in which the wavelengths are spread out, with the slit perpendicular to it.",
