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

非球面镜


Definition from photography forum:
非球面镜是为了校正球面像差而开发出来的,通过修改镜片表面的曲率,让近轴光线与远轴光线所形成的焦点位置重合, 以校正广角等摄影方式带来的像面边缘扭曲。

Example sentence(s):
  •  非球面镜用以消除彗星像差与耀光,尽量矫正像面弯曲、歪曲像差,由於一枚非球面镜的矫正能力等於多枚球面镜片,因此镜头中使用非球面镜片可以达到轻量化。 - forum  
  • 镜头采用了非球面镜片可使镜头出现的“球面光差”(Spherical Aberration、国内称球面像差)得到适当的解决。 - Chinese photography  
  • 非球面镜片改变了镜片呈现非球面的弧度,从镜片边缘看,你发现坡度不是完美的弧形。 - IT  

Explanation:
从英文的例子和定义看这个"非球面镜"是在摄影领域的. 在中文中一种眼镜镜片也叫非球面镜, 但和摄影的非球面镜有所区别.
