Abstract

ELEMENTO OPTICO (12) QUE TIENE SUPERFICIES OPTICAS ASFERICAS (14) Y BINARIAS DE RETICULA (16). EN LA PRESENTACION PREFERIDA, EL ELEMENTO OPTICO (12) ES UN ELEMENTO OPTICO DE MENISCO POSITIVO, HECHO DE GERMANIO, QUE TIENE UNA BANDA PASANTE ESPECTRAL UTIL EN LA REGION DE LAS LONGITUDES DE ONDA DEL INFRARROJO. UN TELESCOPIO (100) INCLUYE UN PRIMER ELEMENTO OPTICO DE MENISCO POSITIVO (102), QUE TIENE UNA SUPERFICIE ASFERICA CONVEXA (104), Y UNA SUPERFICIE CONCAVA BINARIA RETICULAR (106). SE EMPLEA UN PRIMER ELEMENTO OPTICO DE MENISCO NEGATIVO (107) QUE TIENE UNA SUPERFICIE CONCAVA BINARIA RETICULAR (108) Y UNA SUPERFICIE CONCAVA ASFERICA (110). A CONTINUACION, EXISTE UNA LENTE DE AUMENTO POSITIVA (112), SEGUIDA DE UNA SEGUNDA LENTE DE MENISCO NEGATIVO (118). EN LA PRESENTACION PREFERIDA EL PRIMER ELEMENTO OPTICO DE MENISCO NEGATIVO (107) Y LA LENTE DE AUMENTO POSITIVA (112) ESTAN INCORPORADAS EN UN ALOJAMIENTO COMUN (124), QUE ES DESMONTABLE DEL SISTEMA DEL TELESCOPIO. LA SEPARACION DEL ALOJAMIENTO (124) CONVIERTE AL SISTEMA DEL TELESCOPIO (100) DE UN TELESCOPIO DE CAMPO DE VISION AMPLIO (100), EN UN TELESCOPIO DE CAMPO DE VISION ESTRECHO (40).
