From Wikipedia, the free encyclopedia

A simulation of spherical aberration in an optical system with a circular, unobstructed aperture admitting a monochromatic point source. These are longitudinal sections through the focus, and scaled to f/1. Inside focus is to the left, and outside-focus is to the right (i.e., light is propagating left to right). The top image is over-corrected (half a wavelength), the middle image is perfectly corrected, and the bottom image is under-corrected (half a wavelength). Note the left/right reversal of the top and bottom images. While this simulation was computed under the rubric of fourier optics, you can compare these images to commonly drawn diagrams in geometric optics. See also the corresponding focal plane images.
