コリメート光とは、ビーム内のどの光線もが他の全ての光線と平行になっている状態を表します。コリメート光を作るには、正の焦点距離をもつ光学系から焦点距離分離れた位置に非常に小さな光源を配置するか、或いは無限遠から点光源を観察するかのいずれかで可能になります。

Color-corrected optical lenses are ideal for many applications because they reduce multiple aberrations. Learn more about the advantages at Edmund Optics.

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。
