  "term": "Spectrograph",
  "field": "Meteorology and atmospheric science",
  "definition": "An optical instrument designed to separate incident electromagnetic radiation into its constituent wavelengths and record the resulting spectrum. It typically consists of an entrance slit, a dispersive element like a prism or diffraction grating, and a detector array. The output provides a detailed analysis of the spectral distribution of light, which is used to identify atmospheric gases or aerosols.",
