Correcting optical aberrations

Patent Granted An optical aberration is a departure of the performance of an optical system from the predictions of paraxial optics.[1] 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.
