Abstract
TUBO DE IMAGEN DE COLOR. COMPRENDE, EN UNA AMPOLLA CON VACIO INTERIOR, UNA PANTALLA DE IMAGEN Y UN SISTEMA DE CAÑONES DE ELECTRONES. ESTE ULTIMO GENERA TRES HACES DE ELECTRONES SITUADOS EN UN PLANO, Y DISPONE DE UN SEGUNDO ELECTRODO FORMADO POR UNA PARTE (40) EN FORMA DE VASO, EN LA CUAL ESTA FIJADA UNA PLACA (41) A LA PARTE DE FONDO, Y UNA PLACA (42) EL EXTREMO ABIERTO. DISPONE DE UNA SERIE DE ABERTURAS PARA LOS HACES DE ELECTRONES, QUE PRODUCEN LA GENERACION DE UN CAMPO DE LENTE ASIMETRICA EN DICHO SEGUNDO ELECTRODO (15), DE MODO QUE LOS TRES HACES DE ELECTRONES CONVERGEN SOBRE LA PANTALLA DE IMAGEN. LA DISPOSICION DE LOS EJES DE LOS HACES DE ELECTRONES ORIGINA CAMPOS DE LENTE DE ENFOQUE ASIMETRICA QUE PERMITEN, EN CASO DE VARIACION EN EL POTENCIAL DE LOS ELECTRODOS DE ENFOQUE (18, 19, 20, 21), QUE SOLO RESULTE INFLUIDO EL ENFOQUE, Y NO LA CONVERGENCIA DE LOS HACES DE ELECTRONES.
