Abstract

La presente invención se refiere a un cinescopio que tiene un cañón electrónico para generar y dirigir tres haces electrónicos a lo largo de trayectorias hacia una pantalla del cinescopio; incluyendo el cañón electrodos que comprenden una región formadora de haz y electrodos para formar una lente enfocadora principal; caracterizado porque comprende electrodos en el cañón electrónico para formar una lente multipolar entre la región formadora de haz y la lente enfocadora principal en cada una de las trayectorias de haz electrónico; en donde los electrodos para formar una lente multipolar inclyyen un primer electrodo de lente multipolar y un segundo electrodo de lente multipolar; siendo el segundo electrodo de lente multipolar una porción de uno de los electrodos para formar la lente enfocadora principal, y estando situado el primer electrodo de lente multipolar entre el segundo electrodo de lente multipolar y la región formadora de haz, adyacente al segundo electrodo de lente multipolar; y cada lente multipolar está situada suficientemente cerca de la lente enfocadora principal para hacer que la fuerza de la lente enfocadora principal varíe en relación con la resistencia de la lente multipolar.
