Patent number: 9817155Abstract: The present invention relates to an optical lens having a lens element produced of plastic, more particularly of plastic which is transparent in a visible spectral range, and having a coating comprising a plurality of layers, the plurality of layers comprising at least one high-refractive-index layer. Furthermore, a hardcoat layer is formed adjacent to the lens element, and a superhydrophobic layer concludes the coating in opposition to the lens element. The at least one high-refractive-index layer has a thickness of less than 40 nm, and the coating overall has a thickness of more than about 380 nm.Type: GrantFiled: February 9, 2015Date of Patent: November 14, 2017Assignee: CARL ZEISS VISION INTERNATIONAL GMBHInventor: Andreas Neuffer

Patent number: 9778484Abstract: An optical element has a substrate body made from transparent plastic and a coating having multiple layers. The coating includes a hard lacquer layer adjoining the substrate. The coating has a diffusivity ensuring the absorption of water molecules passing through the coating in the substrate and the release of water molecules from the substrate through the coating from an air atmosphere on that side of the coating facing away from the substrate with a flow density which, proceeding from the equilibrium state of the quantity of water molecules absorbed in the substrate in an air atmosphere at 23° C. and 50% relative humidity, brings the setting of the equilibrium state of the quantity of water molecules absorbed in the substrate in an air atmosphere at 40° C. and 95% relative humidity within an interval not more than 10 h longer than for setting this equilibrium under corresponding conditions with an identical uncoated substrate.Type: GrantFiled: May 6, 2014Date of Patent: October 3, 2017Assignee: Carl Zeiss Vision International GmbHInventors: Norbert Hugenberg, Markus Haidl, Bernhard von Blanckenhagen, Lothar Holz, Stefan Kraus, Frank Macionczyk, Michael Krause, Erwin Green, Karl-Heinz Winter, Thomas Gloege, Silvia Faul, Anja Petereit, Bin Peng, Joerg Puetz, Patrick Kiefer, Adalbert Hanssen, Michael Krieger, Andreas Neuffer, Marc Stroisch

Patent number: 9778170Abstract: Determining a barrier effect of a coating for a medium includes: providing a substrate having the coating on its surface, the substrate undergoing a volume change on contact with the medium; conditioning the substrate with the coating; removing the coating from a first part of the surface, leaving the coating on a second part, the first part having an extent in a first direction delimited by the coating remaining on the second; determining a height profile of the coating on the second part and the first part on a path in the first direction; exposing the remaining coating and the first part to the medium; determining a second height profile of the coating on the second part and the first part on the path in the first direction and/or determining a difference in height profile on the second and first part with respect to the height profile determined beforehand.Type: GrantFiled: March 27, 2017Date of Patent: October 3, 2017Assignee: Carl Zeiss Vision International GmbHInventor: Andreas Neuffer
