Abstract

ESTA INVENCION PROPORCIONA UNA MICROLENTE CILINDRICA (10) CON DIFRACCION LIMITADA, Y APERTURA NUMERICA ALTA. EL METODO PARA LA FABRICACION DE LA MICROLENTE SE PUEDE ADAPTAR PARA PRODUCIR UNA LENTE CILINDRICA (10) QUE TIENE CASI CUALQUIER FORMA EN SUS SUPERFICIES OPTICAS. LA LENTE CILINDRICA (10) PUEDE TENER UNA FORMA, TAL COMO LA ELIPTICA O LA HIPERBOLICA, DISEÑADA PARA TRANSFORMAR UNA DISTRIBUCION DE LUZ DE ENTRADA DADA EN PARTICULAR EN UNA DISTRIBUCION DE LUZ DE SALIDA DESEADA. EN EL METODO, LA FORMA DESEADA SE FORMA PRIMERO EN UN COMPUESTO PREFORMADO DE CRISTAL (20). DESPUES, SE CALIENTA EL COMPUESTO PREFORMADO (20) A LA TEMPERATURA DE REVENIDO MINIMA Y SE SACA DE ESTO UNA FIBRA. LA FORMA TRANSVERSAL DE LA FIBRA MANTIENE UNA RELACION DIRECTA CON LA FORMA DEL COMPUESTO PREFORMADO (20) DEL QUE SE HA SACADO. DURANTE EL PROCESO DE EXTRACCION, LAS SUPERFICIES (22, 24) SE VUELVEN OPTICAMENTE LISAS DEBIDO A LA PULIMENTACION POR EL FUEGO. LA PRESENTE INVENCION TIENE MUCHAS APLICACIONES, TALES COMO LA OPTICA INTEGRADA, DETECTORES OPTICOS Y DIODOS LASER.
