Chromatic and Monochromatic Aberrations
... Everything you have learned about object and image formation is an approximation. When light is refracted by spherical surfaces the rays do not all converge to a point, even if they are of one wavelength. Monochromatic aberrations can arise from surfaces with irregularities (The human eye is a good ...

These correspond to the two classical “aplanats,” with one surface at which the incident and refracted marginal ray angles are proportional to the refractive indices, and ...

... So far, we haven’t asked what the functional form of W might be. If we restrict ourselves to rotationally symmetric optical systems, we can limit the possible forms W might take. If we assume a 2-Dimensional polynomial form for W, and eliminate all terms and combination of terms that are not rotatio ...

Optical aberration

An optical aberration is a departure of the performance of an optical system from the predictions of paraxial optics. In an imaging system, it occurs when light from one point of an object does not converge into (or does not diverge from) a single point after transmission through the system. Aberrations occur because the simple paraxial theory is not a completely accurate model of the effect of an optical system on light, rather than due to flaws in the optical elements.Aberration leads to blurring of the image produced by an image-forming optical system. Makers of optical instruments need to correct optical systems to compensate for aberration.The articles on reflection, refraction and caustics discuss the general features of reflected and refracted rays.
