Abstract

UNA LENTE DE ZOOM (10) TIENE UN PRIMER GRUPO DE LENTES (12), UN SEGUNDO GRUPO DE LENTES (14) Y UN TERCER GRUPO DE LENTES (16). EL PRIMER GRUPO DE LENTES RELEGA UNA ESCENA EXTERIOR A UN PLANO INTERMEDIO, EL SEGUNDO GRUPO DE LENTES VARIA LA AMPLIFICACION DE LA IMAGEN RELEGADA DEL PRIMER GRUPO DE LENTES. TAMBIEN, EL SEGUNDO GRUPO DE LENTES INCLUYE AL MENOS UN ELEMENTO OPTICO DIFRACTIVO. EL TERCER GRUPO DE LENTES COMPENSA EL DESPLAZAMIENTO DEL FOCO Y ENFOCA LA IMAGEN SOBRE EL PLANO DE VISION.
