асфералық линза

асфералық линза

A lens with a curved, non-spherical surface. Used to reduce aberrations and achieve a more compact lens size. With a spherical lens, rays travelling from the lens periphery create the image before the ideal focal point and give a blurred image centre. With an aspherical lens, even the rays travelling from the lens periphery converge at the ideal focal point, thus producing a sharp image.
