Nuevo espejo elíptico caracterizado por el hecho de que en el borde del orificio central y en el de la base del espejo hay situados sendos aros de sección en "U" aplicados contra los bordes del espejo cuales aros preservan los aludidos bordes de las corrientes de aire frio que se producen en las linternas cinematográficas que al rozar con los bordes del espejo producirían la rotura del mismo de no existir tal protección.
