  • Patent number: 10907249
    Abstract: Methods and apparatuses for coating a flexible substrate are provided. The flexible substrate is guided over a process roller. The flexible substrate has a first protective film, which is removed from the flexible substrate before the flexible substrate reaches a coating zone of a coating device located opposite the process roller. The first protective film is removed from the flexible substrate after the flexible substrate has formed a mechanical contact with the surface of the process roller. A second protective film is applied to the coated side of the flexible substrate after the flexible substrate has left the coating zone of the coating device and before the mechanical contact between the process roller and the flexible substrate is ended.

  • Publication number: 20180321424
    Abstract: A method for the production of nanoscopic and/or microscopic surface structures on a flat substrate is provided, wherein the surface structure of the substrate is changed through the use of an ion etching process. First, a coating that features a boundary surface-active substance with a concentration of 0.01 to 5 percent by weight is applied to the substrate. The coating applied to the substrate is subsequently transformed into a solid form, and the ion etching process is then performed.

  • Patent number: 8625201
    Abstract: An optical element for distributing light has a predefined spectral energy distribution in a predetermined working wavelength range. The optical element encompasses a transparent body into which the light enters, and a beam splitter layer embodied inside the transparent body, which layer has in the working wavelength range a predefined wavelength-dependent reflectance with which it reflects the light entering the transparent body in order to generate a reflected exit light bundle, and a wavelength-dependent transmittance with which it transmits the light entering the transparent body to generate a transmitted exit light bundle. The optical element encompasses a compensation layer arrangement, embodied on the transparent body separately from the beam splitter layer, whose transmittance with regard to the light passing through the compensation layer arrangement is defined as a function of the reflectance and transmittance of the beam splitter layer.
