Aberration can be defined as a departure of the performance of an optical system from the predictions of paraxial optics. [2] 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. See more In optics, aberration is a property of optical systems, such as lenses, that causes light to be spread out over some region of space rather than focused to a point. Aberrations cause the image formed by a lens to be blurred or … See more In a perfect optical system in the classical theory of optics, rays of light proceeding from any object point unite in an image point; and therefore the object space is reproduced in an … See more The classical imaging problem is to reproduce perfectly a finite plane (the object) onto another plane (the image) through a finite … See more • Aberrations of the eye • Optical telescope § The five Seidel aberrations • Wavefront coding See more With an ideal lens, light from any given point on an object would pass through the lens and come together at a single point in the image plane (or, more generally, the image surface).
