Aberration(1) A deviation or irregularity. For example, a chromosome aberration is a deviation from the normal chromosome number or the normal chromosome structure. In this sense, aberration is also synonymous with deflection, departure, divergence, diversion, turning. (2) A mental aberration is a significant deviation from normal mental activity. In this se [..]

Aberrationn. Deviation from a right, customary, or prescribed course.

AberrationProperty of an optical system that causes an image to have certain easily recognisable flaws. Aberrations are caused by geometrical factors such as the shapes of surfaces, their spacing, and alignments. Image problems caused by factors such as scratches or contamination are not called aberrations.

Aberrationnoun. 1. a departure from one's average behavior. 2. in regard to eyesight, when beams of light do not correctly meet at the target area-the result of a lens malfunction or deformation.

AberrationThe blurring or distortion of an image in the optical system of a microscope. It is classified into monochromatic and color aberration. Monochromatic has five types - spherical, comatic, astigmatism, [..]

AberrationThe apparent change in position of a light-emitting object due to the constancy of the speed of light and the motion of the observer relative to the emitter. The effect is nonrelativistic; that is, special relativity is not required to derive it: all that is needed is Newtonian mechanics and the assumption of the constancy of the speed of light [..]

Aberration(n) a state or condition markedly different from the norm(n) a disorder in one's mental state(n) an optical phenomenon resulting from the failure of a lens or mirror to produce a good image
|

AberrationIs a difference in the position of a star due to the motion of the earth.
|
13 |
AberrationIs caused by the dispersion of the lens material, the variation of its refractive index n with the wavelength of light. Since the focal length f of a lens is dependent on n, if follows that different wavelengths of light will be focused to different positions. Chromatic aberration of a lens is seen as fringes of color around the image.

15 |
AberrationAn optical aberration is a departure of the performance of an optical system from the predictions of parallel axis optics. In a spectrometer, an optical aberration is typically seen when light from a single point does not converge back into a point after passing through the system and is seen as a “blur” or “smear” in the spectrum. Aberrations are [..]

AberrationImage distortion and colour changes caused by the spherical surface of the lens. A common lens problem, it reduces sharpness and contrast, and causes images to become wavy or curved. Aspherical lenses minimize aberration.

AberrationOptical problem in a camera lens that produces slight errors in subject appearance, usually noticeable in small details.

AberrationThe failure of a mirror, refracting surface, or lens to produce exact, point-to-point correspondence between an object and its image.
|
21 |
AberrationFailing in the ability of a lens to produce a true image. There are many forms of aberration and the lens designer can often correct some only by allowing others to remain. Generally, the more expensive the lens, the less its aberrations (More attention to optical quality). While no single lens is called a 'perfect lens'. The "id [..]

AberrationA distortion of image quality or color rendition in a photographic image caused by optical limitations of the lens used to capture the image. Commonly found on the edge of photographs, looks like "smearing."

AberrationAbnormal number or structure of Chromosomes. Chromosome aberrations may result in Chromosome Disorders.

AberrationAbnormal number or structure of the Sex Chromosomes. Some sex Chromosome Aberrations are associated with Sex Chromosome Disorders and Sex Chromosome Disorders of Sex Development.

AberrationA genetic or environmentally produced variation on the usual form of the species. For example very cold conditions can produce very dark forms of some species.

Aberration1. <ophthalmology> Any error that results in image degradation. Such errors may be chromatic, spherical, astigmatic chromatic, distortion, or curvature of field: and can result from design or execution, or both. 2. <physics> Failure of an optical or electron-optical lens to produce exact geometrical (and chromatic) correspondence betwee [..]

31 |
Aberration<optics> A defect in a lens or optical system due to the greater refraction of shorter wavelengths over that of loner ones at a lens surface. Hence the focal length of a simple lens is shorter for blue than for red rays. This dispersion of the wave-lengths will cause colour fringes in the image field of a lens with such an aberration. (05 Aug [..]

32 |
Aberration<optics> A lens defect whereby image forming rays of one colour, passing through the outer zones of a lens come to focus at a different distance from the lens than do those of more central rays. With a simple spherical (or plano-spherical) lens the outer rays always meet the axis closer to the lens than do more central rays and the lens is un [..]
