Abstract: A process is described for modification of a surface of a substrate by ion bombardment, in which the ions are produced by means of a magnetic field-assisted glow discharge in a process gas. The magnetic field-assisted glow discharge is produced by means of a magnetron having an electrode and at least one magnet for production of the magnetic field. The process gas has at least one electronegative constituent, such that negative ions are produced in the magnetic field-assisted glow discharge, and the negative ions which are produced at the surface of the electrode are accelerated in the direction of the substrate by an electrical voltage applied to the electrode.

Abstract: A method for manufacturing an optical waveguide layer includes a substrate that is prepared, onto which a first part-layer is first grown. Subsequently, a second part-layer of the waveguide layer, consisting of the same material as the first part-layer, is grown on the first part-layer. The second part-layer is bombarded with ions as it grows. The method permits manufacturing optical waveguide layers on temperature-sensitive polymer substrates.

Abstract: The invention relates to an optical system for reducing the reflection of optically transparent substrates. A layer system consisting of alternately arranged layers is formed on the surface of the respective substrate. The aim of the intention is to reduce the proportion of reflected light within a broad wavelength range, whereby it is possible to have a specific influence upon the value of the reflection, the respective wavelength range wherein a reduction is obtained, and, optionally, upon a colour impression arising therefrom. According to the invention, the alternately arranged layers of materials having lower and higher optical refraction indexes form stacks of layers. Said stacks of layers have an equivalent optical refraction index, in relation to a predefinable wavelength lambda, which is lower than the optical refraction index of the substrate.

Abstract: The invention relates to a method and a mold for producing transparent optical elements from polymeric materials. In this case, the optical elements that can be produced in this way are intended to have at least surface regions which have reduced interfacial reflection. According to the invention, the procedure followed here is that, in the case of a reference element which consists of a polymeric material and corresponds to the respective optical element, the entire surface or a correspondingly selected surface is exposed to the influence of high-energy ions in a vacuum. In this way, an irregular nanostructure with alternately arranged elevations and depressions lying in between is formed on the corresponding surfaces. Subsequently, a thin electrically conducting layer is applied and electrochemical forming is carried out in order to obtain a mold with a negative contour which is superposed by the nanostructure.

In particular, the invention can be advantageously employed on surfaces of substrates such as optical elements and spectacle glasses, in particular.

With this, a coating is deposited in which the sum of the layer thicknesses of layers each having a higher refractive index is ≦5% of the total layer thickness of the coating, and the layers of the material having a higher refractive index within the layer sequence of the change layer system are uniformly distributed.
