Abstract

L'invention concerne les dispositifs électroniques. Le dispositif faisant l'objet de l'invention est caractérisé en ce que le système de focalisation comporte, afin d'assurer la constance de la focalisation du faisceau d'électrons sur l'écran 9, une lentille de puissance variable 11 située entre l'électrode d'accélération 6 et la deuxième électrode 8 du système de focalisation et destinée à maintenir constante la focalisation du faisceau d'électrons lors des fluctuations de l'énergie des électrons de ce dernier. L'invention peut être utilisée notamment dans les systèmes de visualisation d'informations.
