WebJan 21, 2024 · The influence of the primary aberration coefficient on the intensity distribution, longitudinal field and the quality of the aberrated focused field are analyzed. … 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 distorted, with the nature of the distortion depending on the type of aberration. … 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). Real lenses do not focus light exactly to a … See more The classical imaging problem is to reproduce perfectly a finite plane (the object) onto another plane (the image) through a finite aperture. It is impossible to do so perfectly for more than one such pair of planes (this was proven with increasing generality … See more • Aberrations of the eye • Optical telescope § The five Seidel aberrations • Wavefront coding 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 image space. The introduction of simple auxiliary terms, due to See more The preceding review of the several errors of reproduction belongs to the Abbe theory of aberrations, in which definite aberrations are discussed separately; it is well suited to practical needs, for in the construction of an optical instrument certain errors are … See more In optical systems composed of lenses, the position, magnitude and errors of the image depend upon the refractive indices of the glass … See more • Microscope Objectives: Optical Aberrations section of Molecular Expressions website, Michael W.
