Abstract: An inkjet method for producing a spectacle lens and fluids that can be used in an inkjet method for producing a spectacle lens are disclosed. The inkjet method includes the following steps: a) providing a substrate to be printed on, b) applying to the substrate to be printed on from step a) at least two volume elements applied adjacently and/or adjoining one another, c) transferring the at least two volume elements applied adjacently and/or adjoining one another from step b) into at least one volume composite, d) transferring the at least one volume composite from step c) into at least one homogeneous volume composite, e) transferring the at least one homogeneous volume composite from step d) into at least one final volume composite.

Abstract: The disclosure relates to a device for mounting two spherical optical components. The device includes a first holder, having a receptacle for a first optical element with a first spherical convex face with a first radius, and a second holder, having a receptacle for a second optical element with a second spherical optical concave face with a second radius. At least one of the holders has a supporting face with a third radius, and the first holder can be supported on the second holder such that the radii have a common center point when the first optical element is held in the first holder and the second optical element is held in the second holder.

Abstract: A spectacle lens has a transparent substrate and at least one HOE-capable polymer layer arranged on the transparent substrate. The at least one HOE-capable polymer layer is suitable for forming a holographic optical element. Related methods and apparatus are described.

Abstract: A material including a glass or vitroceramic substrate having a first layer and a second layer deposited thereon, each of the first and second layers including at least one transparent conducting oxide (TCO). The first layer has a roughness of more than 1 nm and the second layer has a roughness less than or equal to 1 nm. A transmittance in the visible wavelength range of the material is at least 80%. The work function of the second layer is greater than the work function of the first layer and is greater than 4.6 eV.

Abstract: A process for depositing a layer of product on at least part of a major surface of a substrate having two sides separated by a thickness of less than about 3 mm is provided.
