Record 2 2004-04-04

English

Subject field(s)
  • Optics
  • Photography
DEF

A defect in an optical system that results in points on an object plane perpendicular to the axis being imaged on a curved surface rather than on a plane.

French

Domaine(s)
  • Optique
  • Photographie
DEF

Aberration d'un système optique centré, qui se manifeste par le fait que l'image d'un objet plan, perpendiculaire à l'axe et suffisamment étendu, n'est pas plane.

OBS

L'image se forme sur une surface courbe de révolution autour de l'axe. La courbure de champ, de même que l'astigmatisme, nuit à la netteté des images des points éloignés du centre du champ.
