Abstract

En rapprochant par déviation des champs de lentilles non symétriques dans un système de canons électroniques vers l'axe du tube de façon à obtenir leur convergence sur l'écran image, il est possible, dans le cas où le faisceau forme un angle déterminé avec les axes des canons, d'obtenir des champs constituant des lentilles de focalisation symétriques avec des électrodes non symétriques parallèles, ce qui permet une réalisation facile des électrodes et un montage précis des canons. Dans ces canons, la focalisation des faisceaux n'est pas tributaire de la convergence. Application : tube image de télévision en couleurs.
