Abstract

Procedimiento de fabricación de lentes y otros medios ópticos, en resinas sintéticas, por medio de la colada de un monómero catalizado que se polimeriza hasta endurecerse por medio de calor, al interior de un molde formado por dos o más lentes de vidrio ensambladas la una a la otra por medio de un empaque perimétrico y un resorte, caracterizado por el hecho de compensar la retracción del polímero en curso de formación por medio de monómero catalizado, puesto al exterior del molde en presencia de aire, de manera que pueda fluir hacia el interior del molde que se encuentra en ausencia de aire.
