Abstract

L'invention concerne des lentilles d'étalement du balayage pour tubes cathodiques. Ces lentilles se caractérisent par quatre éléments 44, 45, 46, 47 successifs qui sont séparés par des intervalles 48, 49, 50 incurvés différemment et qui sont reliés à des potentiels différents, afin de former un système convergent dans une direction et divergent dans la direction orthogonale. Ces lentilles s'appliquent aussi bien à des tubes à une seule accélération qu'à des tubes à accélération après déflexion.
