scope note
  • Plan-konvexe Linse, die durch die Reduzierung der konvexen Seite zu einer Reihe von konzentrischen Ringen von etwa der gleichen Brennweite verdünnt ist; wenn Licht hindurchfällt, erzeugt sie einen gleichmäßigen, weichen Lichtstrahl. (de)
  • 將凸面降為一串焦距大致相同之共中心環，以減少鏡片厚度的平凸透鏡；當光線穿透時，會製造出一種平滑、柔和的光芒。 (zh-hant)
  • Plano-convex lenses thinned by reducing the convex side to a series of concentric rings of approximately the same focal length; when light passes through, it produces a smooth, soft-edged beam of light. (en)
