Single-beam spectrometer

  "id": "MLC-T-CHM-010893",
  "term": "Single-beam spectrometer",
  "field": "Chemistry",
  "definition": "An optical instrument that directs a single beam of radiation through a sample to measure its absorbance or transmittance. The intensity of the transmitted light is compared to a separate measurement of the incident light intensity, often obtained from a blank or reference. This design is simpler than a double-beam spectrometer but requires careful background correction.",
