  • Publication number: 20210164092
    Abstract: The invention relates to a device and a method for producing layers with very good uniformity in coating systems with horizontally rotating substrate guiding. Alternatively, certain layer thickness gradients can be set. The particle loading is also significantly reduced. The service life is much higher compared to other methods. Parasitic coatings are reduced. The coating rate is also increased.

  • Publication number: 20180136369
    Abstract: A coated object and a method for producing a coated object are disclosed. In an embodiment, the coated object includes a substrate and an optical coating disposed on the substrate, wherein the optical coating includes a reflection-reducing layer sequence, which includes a covering layer with a refractive index nA and at least one diamond layer with a refractive index nD1>nA, wherein the diamond layer is disposed between the covering layer and the substrate and includes diamond crystals, and wherein the diamond layer has a layer thickness of less than 500 nm.

  • Publication number: 20170371224
    Abstract: The invention relates to an electrically controlled interference colour filter comprising at least two transparent electrodes, at least one nematic liquid crystal layer and alignment layers for alignment of the liquid crystals. When an electrical field is applied the liquid crystals can be realigned and thus the transmission wavelength range of the interference colour filter can be shifted.

  • Publication number: 20140233106
    Abstract: An object with reflection-reducing coating includes a substrate and a coating arranged on the substrate. The coating is multilayered and includes an outer layer having a refractive index n1 and at least one second sub-layer with a refractive index n2 which is adjacent to the outer layer. n2>n1+0.4, and the outer layer possesses a refractive index n1>1.50 and a layer hardness greater than 8 GPa.

  • Publication number: 20120164051
    Abstract: The present invention relates to a method for the enhanced production of insulating layers by High Power Impulse Magnetron Sputtering (HiPIMS) or High Power Pulsed Magnetron Sputtering (HPPMS). This method is preferably used for the production of oxynitride layers with variable amounts of oxide and nitride, preferably based on silicon and aluminium.
