  • Patent number: 8137742
    Abstract: A sub-stoichiometric oxide, nitride or oxynitride layer in an optical stack, alone or in direct contact with one or two stabilizing layers, stabilizes the optical properties of the stack. The stabilizing layer(s) can stabilize the chemistry and optical properties of the sub-stoichiometric layer during heating. The change in optical characteristics of the sub-stoichiometric layer upon heating can counter the change in optical characteristics of the rest of the optical stack.

  • Patent number: 7883776
    Abstract: An optical coating on a transparent substrate is provided with a temporary layer of carbon as protection during manufacturing against scratches and corrosive environments. When the optical coating and/or substrate are tempered in an atmosphere reactive to carbon, such as air, the layer of carbon is removed as a carbon-containing gas. For an optical coating with a brittle, glassy, outermost layer furthest from the substrate, additional protection is provided by a scratch propagation blocker layer between the outermost layer and the carbon protective layer.

  • Publication number: 20070258093
    Abstract: An apparatus for measuring the reflectance properties of an object having a front reflecting surface and at least one back reflecting surface. The apparatus includes a sample stage for placement of the object, a light source, a detector configured to detect reflected light from the object, and a positioning device configured to provide a plurality of angular positions for the light source and the detector relative to the object on the sample stage such that incident light on the object is specularly reflected towards the detector and the reflected light received at the detector includes a front surface reflection from the object and at least one back surface reflection from the object.

  • Publication number: 20060134436
    Abstract: The present invention provides a scratch protecting layer comprising a metal, metal alloy, metal compound or an intermetallic layer deposited on an air contacting surface. The scratch protecting layer is typically from 1 to 3 nanometers thick and not optically absorbing after oxidation occurs. This layer is initially deposited in a primarily unoxidized or un-nitrided state. Full oxidation of the metal, metal alloy, metal compound or intermetallic layer occurs within several days after exposure to air. The scratch protection layer can be 2 to 5 nanometers thick if the layer is exposed to a plasma, electrical discharge or ion beam comprising a reactive gas such as oxygen or nitrogen.
