Abstract

PARA MEDIR LA CALIDAD OPTICA DE L SUPERFICIE DE UNA PLACA TRANSPARENTE, SE PONE LA SEGUNDA SUPERFICIE DE LA PLACA EN CONTACTO CON UN MATERIAL FLEXIBLE MOJADO POR UN LIQUIDO DE INDICE. EN EL CASO DEL VIDRIO SILICO-SODO-CALCICO, EL AGUA ES APROPIADA. LA MEDICION OPTICA PROPIAMENTE DICHA PUEDE HACERSE POR TODOS LOS METODOS HABITUALES EN PARTICULAR POR SOMBROSCOPIA. APLICACION EN LA SELECCION DE LOS VIDRIOS DESTINADOS A SER EMPAREJADOS PARA REALIZAR LUNAS LAMINADAS O PANTALLAS PLANAS.
