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...

In optics, chromatic aberration (CA), also called chromatic distortion, color aberration, color fringing, or purple fringing, is a failure of a lens to...

In optics, spherical aberration (SA) is a type of aberration found in optical systems that have elements with spherical surfaces. This phenomenon commonly...

other optical system, suffers from a number of specific optical aberrations. The optical quality of the eye is limited by optical aberrations, diffraction...

Defocus aberration, in which an image is out of focus Optical aberration, an imperfection in image formation by an optical system Relativistic aberration, the...

the coma (/ˈkoʊmə/), or comatic aberration, in an optical system refers to aberration inherent to certain optical designs or due to imperfection in...

third-order aberration, which occurs for objects (or parts of objects) away from the optical axis. This form of aberration occurs even when the optical system...

curvature, named for Joseph Petzval, describes the optical aberration in which a flat object normal to the optical axis (or a non-flat object past the hyperfocal...

unambiguous picture is provided by the optical transfer function. Optical systems, and in particular optical aberrations are not always rotationally symmetric...

is a form of optical aberration that may be distinguished from other aberrations such as spherical aberration, coma, chromatic aberration, field curvature...
