| has gloss | (noun) (optics) condition of an optical system (as a lens) in which light rays from a single point converge in a single focal point stigmatism |
| has gloss | eng: In geometric optics, stigmatism refers to the image-formation property of an optical system which focuses a single point source in object space into a single point in image space. Two such points are called a stigmatic pair of the optical system. Many optical systems, even those exhibiting optical aberrations including astigmatism, have at least one stigmatic pair. Stigmatism is applicable only in the approximation provided by geometric optics. In reality, image formation is at best diffraction limited and point-like images are not possible. |

| has gloss | fra: Un système optique est dit stigmatique si tout faisceau issu dun point lumineux donne à la sortie du système, un faisceau convergeant en un point, ou semblant provenir dun point. Autrement dit, si tout rayon émis par un point lumineux donne après passage dans le système optique un rayon dont le support (une droite) est concourant avec tous les autres supports (ceux des autres rayons après passage dans le système optique) en un même point. Ce point est appelé image. |

| has gloss | ind: Pada optika geometris, stigmatisme (en:stigmatism merupakan kinerja suatu sistem optik yang memfokuskan sebuah titik (en:single point source) pada bidang fokus menuju ke sebuah titik api (en:focal point) pada bidang fokal. Kedua buah titik tersebut berpasangan yang disebut stigmatic pair. |
