Abstract

ESTE APARATO PARA LA MEDICION DE PARAMETROS OPTICOS PARA LENTES OFTALMICAS, COMPRENDE UN SISTEMA DE ALINEAMIENTO OPTICO QUE DISPONE DE UNA VENTANA POR LA QUE EL USUARIO, PORTADOR DE UNA MONTURA DE GAFAS E ILUMINADO POR UNA LUZ DIFUSA, OBSERVA UN OBJETO SITUADO EN EL INFINITO A TRAVES DE UN ESPEJO DICROICO Y REFLEJA EN EL MISMO SU IMAGEN A CAPTAR A TRAVES DE UNA LENTE COFOCAL, LA CUAL IMAGEN ES REFLEJADA POR UN ESPEJO CONVENCIONAL Y, A TRAVES DE OTRO ESPEJO DICROICO, ES CONDUCIDA A UN CAPTADOR DE IMAGEN MATRICIAL, AL TIEMPO QUE UN HAZ DE LUZ VISIBLE E INFRARROJOS, EMITIDA POR UNA FUENTE LUMINOSA MIXTA CONTROLADA POR UN DIAFRAGMA Y UNA LENTE CONDENSADORA, RECORRE INVERSAMENTE EL CAMINO ENTRE LOS ESPEJOS Y LA LENTE COFOCAL HASTA EL USUARIO. ESTE APARATO PERMITE DETERMINAR DE FORMA PRECISA Y RAPIDA LOS PARAMETROS DE MONTAJE DE UNAS LENTES OFTALMICAS SOBRE UNA MONTURA, EVITANDO LOS ERRORES DE PARALELAJE.THIS APPARATUS FOR THE MEASUREMENT OF OPTICAL PARAMETERS FOR OPHTHALMIC LENSES, INCLUDES AN OPTICAL ALIGNMENT SYSTEM THAT HAS A WINDOW BY WHICH THE USER, WEARING A GLASSES FRAME AND ILLUMINATED BY A DIFFUSED LIGHT, IS SITUATED IN A SITUATED OBJECT. THROUGH A DICROIC MIRROR AND REFLECTS ITSELF ON ITS IMAGE TO BE CAPTURED THROUGH A COFOCAL LENS, WHICH IMAGE IS REFLECTED BY A CONVENTIONAL MIRROR AND, THROUGH ANOTHER DICROIC MIRROR, IS CONDUCTED TO A MATRICIAL IMAGE CAPTURER. THAT A BEAM OF VISIBLE AND INFRARED LIGHT, ISSUED BY A MIXED LIGHT SOURCE CONTROLLED BY A DIAPHRAGM AND A CONDENSING LENS, INVERSELY TRAVEL THE ROAD BETWEEN THE MIRRORS AND THE COFOCAL LENS TO THE USER. THIS APPARATUS ALLOWS TO SPECIFICALLY AND QUICKLY DETERMINE THE MOUNTING PARAMETERS OF SOME OPHTHALMIC LENSES ON A MOUNT, PREVENTING PARALLELING ERRORS.
