ABSTRACT:
A low reflectivity, variable attenuation contrast enhancement filter having a total visible light reflectance of less than about 2.0% when measured with light incident to the first outer major surface. The contrast enhancement filter has a first layer(s) for providing antireflection, the first layer(s) defining the first outer major surface; a variable attenuation element interposed between the first major outer surface and the second major outer surface; element(s) for providing fixed attenuation interposed between the variable attenuation element and the first major outer surface; and at least one substrate.
