  • Patent number: 9507320
    Abstract: The invention relates to a method for transferring surface structures such as interference layers, holograms, and other highly refractive optical microstructures to substrates. The aim of the invention is to devise a method which is used for transferring surface structures such as interference layers, holograms, and other highly refractive optical microstructures to substrates and can also be used in a high temperature range. The aim is achieved by a method comprising the following steps: a) a flexible intermediate support layer is applied to a support film as a release layer; b) an embossed sol is applied to the intermediate support layer and is provided with a surface structure; c) a stack encompassing a binder layer and the surface structure is produced; d) the support film is removed; e) the workpiece is thermally treated.

  • Publication number: 20140017399
    Abstract: Disclosed is a substrate with an abrasion resistant and scratch-resistant coating that has a low index of refraction and comprises magnesium fluoride and at least one metal oxide or semimetal oxide. The coating can be obtained by applying a coating composition containing magnesium fluoride or a precursor thereof and at least one metal oxide or semimetal oxide, or a precursor thereof onto a substrate and then subjecting the same to a thermal treatment.

  • Patent number: 8198018
    Abstract: An organic-inorganic hybrid material comprising (a) at least one soluble organic polymer and (b) at least one mono- or polynuclear metal complex having at least one ligand which comprises at least one photochemically and/or thermally polymerizable functional group. Also disclosed is an optical component which is made by using the hybrid material.

  • Patent number: 8133573
    Abstract: A process for producing a crystalline substrate with an optical multi-layer system thereon and the crystalline substrate obtainable thereby. The process comprises the successive application of at least two free-flowing compositions which comprise nanoscale inorganic solid particles comprising at least one of a polymerizable and a polycondensable organic group to a surface of the crystalline substrate and the polymerization and/or polycondensation of the organic groups of the solid particles to form organically crosslinked layers on the substrate and a single-stage thermal consolidation of these layers with a burnout of organic constituents thereof. The at least two compositions give rise to layers with different refractive indices.

  • Publication number: 20080261053
    Abstract: Disclosed is a substrate with an abrasion resistant and scratch-resistant coating that has a low index of refraction and comprises magnesium fluoride and at least one metal oxide or semimetal oxide. The coating can be obtained by applying a coating composition containing magnesium fluoride or a precursor thereof and at least one metal oxide or semimetal oxide, or a precursor thereof onto a substrate and then subjecting the same to a thermal treatment. The inventive coating is suitable for optical layers, particularly on translucent substrates. Examples of adequate uses include antireflection layers and interference layer assemblies.
