Abstract

DISPOSITIVO DE MEDIDA DE LOS PARAMETROS OPTICOS-GEOMETRICOS DE LAS LENTES OFTALMICAS DURANTE EL PROCESO DE FABRICACION. LA INVENCION CONSISTE EN UN DISPOSITIVO DE MEDIDA DE LOS PARAMETROS OPTICOS-GEOMETRICOS (OPTICOS: POTENCIA ESFERICA Y ASTIGMATICA LOCAL Y GEOMETRICOS: RADIO DE CURVATURA PARA SUPERFICIES ESFERICAS Y RADIO DE CURVATURA Y EXCENTRICIDAD PARA SUPERFICIES ESFERICAS) DE LAS LENTES OFTALMICAS DURANTE EL PROCESO DE FABRICACION CARACTERIZADO PORQUE EL ERROR DE FABRICACION EN DICHOS PARAMETROS SE OBTIENEN DE LA COMPARACION ENTRE PATRONES DE SOMBRAS, Y LOS VALORES DE ERROR DE POTENCIA Y ASTIGMATISMO FINALES, SE DERIVAN DE ELLOS. LOS VALORES DE ERROR DE POTENCIA SE CALCULAN A PARTIR DE LAS DIFERENCIAS DE POSICION, MEDIDAS DESDE EL EJE DEL SISTEMA, ENTRE LAS SOMBRAS DE LOS DISTINTOS PUNTOS DE LA RED (FIG. 1, E) REGISTRADOS POR EL SISTEMA OPTICO (FIG. 1, I) Y LOS OBTENIDOS TEORICAMENTE.MEASURING DEVICE FOR OPTICAL-GEOMETRIC PARAMETERS OF OPHTHALMIC LENSES DURING THE MANUFACTURING PROCESS. THE INVENTION CONSISTS OF A DEVICE FOR MEASURING OPTICAL-GEOMETRIC PARAMETERS (OPTICALS: LOCAL AND GEOMETRIC SPHERICAL AND ASTIGMATIC POWER: BEND RADIUS FOR BALL SURFACES AND EXCENTRICITY OF LAND SURFACES). CHARACTERIZED BECAUSE THE MANUFACTURING ERROR IN SUCH PARAMETERS ARE OBTAINED FROM THE COMPARISON BETWEEN SHADOW PATTERNS, AND THE FINAL ERROR VALUES OF POWER AND ASTIGMATISM, ARE DERIVED FROM THEM. THE POWER ERROR VALUES ARE CALCULATED FROM THE POSITION DIFFERENCES, MEASURED FROM THE AXIS OF THE SYSTEM, BETWEEN THE SHADOWS OF THE DIFFERENT POINTS OF THE NETWORK (FIG. 1, E) RECORDED BY THE OPTICAL SYSTEM (FIG. 1, I) AND THOSE OBTAINED THEORICALLY.
