  "term": "Afocal",
  "field": "Industrial and trades",
  "definition": "Describing an optical system where light rays entering parallel emerge parallel, meaning the system has an infinite focal length. This configuration does not form an image at a finite distance. Telescopes and beam expanders often employ afocal designs to magnify or reduce the diameter of a light beam without creating an intermediate image.",
