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.
  • It incorporates a floating focus system and uses two aspherical lens elements for minimizing distortion, spherical aberration and astigmatism. SIGMA CORPORATION

asfärisk lins

Definition from Fotoord:
En asfärisk lins har olika krökning i olika delar till skillnad från en sfärisk lins, där ytan har samma krökning överallt.

Example sentence(s):
  • En asfärisk lins är är slipad så dess krökning ej följer en cirkel. - Fotoord  
  • Ett bättre men dyrare sätt är förse kameran eller kikaren med asfäriska (icke sfäriska) linser som bryter ljuset lika mycket oavsett var en ljusstråle går genom linsen. -
