Abstract

La presente invención se refiere a un sistema de cañón electrónico para un tubo de rayos catódicos en colores, caracterizado porque incluye un elemento de cátodo para desarrollar un haz electrónico, un lente de enfoque principal para recibir el haz electrónico y para formar un punto del haz electrónico enfocado en la pantalla del tubo, el lente de enfoque principal tiene una pluralidad de electrodos situados en un eje común; un elemento para desarrollar y aplicar al electrodo los potenciales efectivos para formar uno o más de los componentes de campo de enfoque entre los electrodos; el lente de enfoque principal se estructura y coloca de manera tal como para ocasionar que se forma entre los electrodos adyacentes por lo menos un componente de campo de enfoque que es asimétrico y efectivo para desviar de manera significativa un haz que ha pasado desde una trayectoria de línea recta a través de un ángulo predeterminado, un primer electrodo de la pluralidad de electrodos consiste de un electrodo de enfoque adaptado para recibir voltajes de enfoque a fin de establecer la distancia de enfoque de los haces, un segundo electrodo de la pluralidad de electrodos coopera con otro de la pluralidad de electrodos para formar el componente de campo asimétrico, y un elemento para desarrollar y aplicar un voltaje variable al segundo electrodo, para ocasionar que la resistencia de componente de campo asimétrico y por lo tanto, del ángulo mediante el cual se desvía el haz, varía en respuesta al voltaje variable.
