Abstract

PARA FACILITAR LA ELIMINACION (11) DE ESPESORES DIFERENTES DE MATERIAL EN UN PROCESO PARA LA CORRECCION DEL PERFIL DE UNA LENTE (2) EN DONDE SE APLICA LA RADIACION A PARTIR DE UNA FUENTE DE RADIACION PULSADA A LA SUPERFICIE DE LA LENTE A TRAVES DE UN DIAFRAGMA (3) EN REGIONES PREDETERMINADAS EXPUESTAS MEDIANTE EL DIAFRAGMA (3), ELIMINANDO CON ELLO MATERIAL A PARTIR DE LA LENTE EN CADA IMPULSO DE RADIACION A TRAVES DEL EFECTO DE RADIACION, DONDE LA RADIACION SE CONCENTRA EN UN HAZ, CUYA SECCION (10) TRANSVERSAL ES MENOS SOBRE EL CEBADO DE SUPERFICIE DE LA LENTE (2) QUE EL AREA EXPUESTA POR MEDIO DEL DIAFRAGMA, Y DONDE EL HAZ SE MUEVE DE TAL MODO, QUE LA INCIDENCIA DE LOS IMPULSOS DE RADIACION SUCESIVOS SOBRE LA SUPERFICIE DE LA LENTE, ESTANDO EXPUESTA LA SUPERFICIE DE LENTE COMPLETA MEDIANTE RADIACION A TRAVES DEL DIAFRAGMA, SE PROPONE QUE EL HAZ SE MUEVA ENTRE IMPULSOS DE RADIACION SUCESIVOS SOLAMENTE HASTA LA EXTENSION REQUERIDA PARA LAS AREAS DE LA SUPERFICIE DE LA LENTE SOBRE LAS CUALESLOS IMPULSOS DE RADIACION INCIDEN DE FORMA PARCIALMENTE SOLAPADA. SE PROPONE TAMBIEN UN DISPOSITIVO PARA LA IMPLANTACION DEL PROCEDIMIENTO.
