Abstract

SE OFRECE UN SISTEMA AFOCAL DE LENTES DE <ZOOM> QUE TIENE PARTICULAR UTILIDAD PARA SU EMPLEO EN SISTEMAS DE AYUDA A LA NAVEGACION AEREA EN LOS QUE ES DESEABLE UN PODER DE AUMENTO UNITARIO (DE 1,0X). SE REVELAN DOS FORMAS DE REALIZACION, DE LAS CUALES LA PRIMERA DE UNA RELACION DE AUMENTOS DE 8:1 (DE MAXIMO A MINIMO AUMENTO) MIENTRAS LA SEGUNDA LA DA DE 12:1. EN AMBAS FORMAS DE EJECUCION SE EMPLEAN CUATRO GRUPOS DE LENTES, QUE INCLUYEN UNA LENTE FRONTAL FIJA DE OBJETIVO (A, E) COMO PRIMER GRUPO UN SEGUNDO GRUPO DE LENTES QUE INCLUYE UN ELEMENTO NEGATIVO DE ACCION DE <ZOOM> (B, F), UN TERCER GRUPO FIJO (C, G) Y UN CUARTO GRUPO QUE COMPRENDE UN ELEMENTO POSTERIOR NEGATIVO DE ACCION DE <ZOOM> (D, H). EL ELEMENTO POSTERIOR DE ACCION DE <ZOOM> Y LA ABERTURA DE DIAFRAGMA SE MUEVEN JUNTOS PARA MANTENER LA COLIMACION DEL HAZ DE SALIDA Y CONSERVAR A UN VALOR CONSTANTE EL DIAMETRO DEL HAZ EN LA SALIDA SEGUN EL EJE.
