Abstract

Procedimiento de obtención de un producto preformado de óptica, caracterizado porque se coloca una pieza de vidrio plano de modo que descanse en múltiples zonas de contacto localizadas, en las cimas de protuberancias de un soporte alveolado formando gofradota monoplaza, y porque se deja que permanezca el conjunto en un horno durante el tiempo necesario para que la materia no soportada de la pieza es decir la que se extiende entre las mencionadas zonas de contacto localizadas se curve hasta la curvatura deseada del ocular ofocal sin que se encuentre en contacto con una superficie material del mencionado soporte alveolado.
