Abstract

Un tubo de rayos catódicos perfeccionado, que tiene una lente electrónica astigmática que comprende al menos dos electrodos dispuestos axialmente uno detrás de otro y medios para aplicar un primer potencial y un segundo potencial a dichos electrodos, teniendo uno de los electrodos en su extremo que mira hacia el otro electrodo medios para formar un campo eléctrico axial y no rotacionalmente simétrico entre los dos electrodos, caracterizado porque la lente electrónica tiene medios de electrodo adicionales a los que puede aplicarse un tercer potencial para el control simultáneo del astigmatismo y la potencia de la lente electrónica.
