The Strehl ratio of an optical system is a comparison of its real performance with its diffraction-limited performance.

非球面アクロマートは、ガラス製の光学レンズ素子に感光ポリマーを貼り合わせて作られます。このポリマーは、ダブレットレンズの片面側だけに貼り合わされるため、短時間内で容易にレプリカを作ることができます。また、一般的なマルチエレメント部品が持つ柔軟性を使用者に提供します。

非球面レンズのメリットは、球面収差を補正する能力です。球面収差は、光の一点集光やコリメートする際に、球面形状の光学素子を使う時に生じます。ここでは非球面レンズの特徴やその性能のメリットから、その製造方法、タイプ別の利点や選定方法を紹介します。
