  • Multi-layer interference filter having colored reflectance and substantially uniform transmittance and methods of manufacturing the same
    Publication number: 20040036973
    Abstract: The present invention is concerned with a new family of optical element for use in eyeglasses, visors, masks and screens which produce a new chromatic effect through a vacuum deposition of two or plus layers of dielectric substances and methods of manufacturing the same. These new filters combine some colored reflection on the outer surface with a uniform transmission looking through the lens so complying the European Standard in terms of luminous transmittance uniformity.
