English: A simulation of spherical aberration in an optical system with a circular, unobstructed aperture admitting a monochromatic point source. The top row is over-corrected (half a wavelength), the middle row is perfectly corrected, and the bottom row is under-corrected (half a wavelength). Going left to right, one moves from being inside focus to outside focus. The middle column is perfectly focused. Also note the equivalence of inside-focus over-correction to outside-focus under-correction. See the corresponding longitudinal sections.
