Abstract

La presente invencion proporciona un filtro que tiene un elemento de material de absorcion entre un lente convexo y un espejo poligonal. Este elemento del material de absorcion es formado revistiendo una película metálica delgada. Debido a lo anterior, se puede proporcionar una distribucion del factor de transmision predeterminada. De acuerdo con esto, es posible corregir una distribucion no uniforme de una cantidad de luz sobre el fotorreceptor, provocada por un cambio en la luminosidad en el sistema optico sobrellenado, de modo que la distribucion de una cantidad de luz pueda ser colocada en uso práctico.
