  "id": "MLC-T-CHM-010938",
  "term": "Slit width",
  "field": "Chemistry",
  "definition": "The physical dimension of the opening that defines the spectral bandwidth of radiation passing through a spectrometer. It directly influences the resolution of the instrument, with narrower slits providing higher resolution but lower light throughput. This parameter is measured in units of length, typically micrometers or millimeters.",
