English term or phrase: aspherical lens
Definition from MIR Web Development Team:
A lens whose curved surface does not conform to the shape of a sphere; lenses are usually ground or molded with spherical surfaces; because a spherical surface lens has difficulty in correcting distortion in ultra-wideangle lenses or coma in large-aperture lenses brought about by spherical aberration, an aspherical lens is used.

Example sentence(s):
  • It incorporates hybrid aspherical lens in the front lens group to minimize distortion and astigmatism, and molded glass aspherical lens in the rear lens group to minimize spherical aberration. Sigma Corporation of America
  • Now found in almost every EF lens, aspherical lens elements are particularly useful for large-aperture lenses, wide-angle lenses and high quality compact zoom lenses. canon.co.uk
  • It incorporates a floating focus system and uses two aspherical lens elements for minimizing distortion, spherical aberration and astigmatism. SIGMA CORPORATION

Definition from Wikipedia:
非球面レンズ(ひきゅうめんれんず)とは、球面のみならず曲面でできているレンズのこと。 球面レンズに比べて収差を小さくすることができるため、カメラや眼鏡のレンズに多く採用されている。

Example sentence(s):
  • 非球面レンズは、カーブの浅い球面レンズの弱点(特に非点収差・湾曲収差)を補正するため、レンズ面がさまざまな曲率半径(球面の曲がり具合)の組み合わせで設計されています。 これにより、レンズ周辺部の収差を少なくすることができるため、浅いカーブ設計のレンズでもより自然な視界を得ることができます。 - http://www.omi.gr.jp/opt/lens/sph-as.htm  
  • 非球面レンズは従来の球面レンズシステムに比べて小型軽量で、単独で集光又は照準できるので、時間もコストも削減され用途も増加しています。 - フォトテクニカ
