A simulation of spherical aberration (top to bottom: over-corrected by ½ wavelength, perfectly corrected, under-corrected; left to right: inside focus, perfectly focused, outside focus)
(optics) A type of lens aberration which causes blurriness, particularly away from the centre of the lens.
1991, Virendra N. Mahajan, Aberration Theory Made Simple, page 27:
For p = -1, the values of q giving minimum spherical aberration (q = 0.71) and zero coma (q = 0.8) are approximately equal to each other.
2002, Michael J. Kidger, Fundamental Optical Design, page 151:
If the refractive index is low, the minimum spherical aberration is not greatly affected by the fact that the second lens operates in a converging beam, and the spherical aberration is approximately equal to h4K3.
2005, Mark Packer, I. Howard Fine, Richard S. Hoffman, “9: Wavefront Technology of Spherical Aberration”, in I. Howard Fine, Mark Packer, Richard Hoffman, editors, Refractive Lens Surgery, volume 1, page 81:
Conventional spherical intraocular lenses (IOLs) have positive spherical aberration.
