  • Patent number: 11851366
    Abstract: The invention relates to a process for connecting glass substrates which allows glass substrates to be aligned in a site-specific manner and to subsequently be connected to one another, and to the site-specifically aligned and interconnected glass substrates. Generally, the process relates to connecting glass substrates to one another, optionally also without site-specific alignment. The interconnected glass substrates obtainable by processes according to the invention are characterized by a firm bond with one another, which is preferably formed by solidified glass solder that is in form-fitting engagement with the glass substrates. Therein, recesses, which are preformed in the glass substrate, with glass solder are used for aligning and optionally for connecting the glass substrates.

  • Publication number: 20230302741
    Abstract: The invention provides a process for producing plastic parts, each of which has at least one glass insert which is connected to the plastic part along a connecting region, and the glass insert is free of plastic in the region encompassed by the connecting region and forms a glass window. The connecting region of the glass insert is preferably circumferentially closed. The glass window can have through-holes or preferably recesses extending only over a portion of the thickness of the glass window and having microstructures.

  • Patent number: 11613803
    Abstract: Use of a laser-activatable component in a composition and/or use of a composition that includes the laser-activatable component, during laser transfer printing, characterized in that the laser-activatable component is activated by laser irradiation during use in such a way that the viscosity and/or the elasticity and/or the tack of the composition increase(s) due to an increase in temperature of the composition, wherein the laser-activatable component is a polymer made up of the groups comprising polyethylene glycol, polyvinylpyrrolidone, polyvinyl acetate, polyvinyl alcohol, polyacrylate, polyester, or copolymers of these polymers or blends.

  • Publication number: 20220388896
    Abstract: The invention relates to a method for producing reaction vessels from glass and to the glass reaction vessels obtainable by this method. The method comprises the following steps: 1. irradiating the surface of a first glass sheet by means of a laser beam of a wavelength for which the first glass sheet is permeable, 2. etching the first glass sheet to form recesses that extend over the complete thickness of the first glass sheet, and 3. connecting a second sheet with a surface of the first glass plate.

  • Publication number: 20220388897
    Abstract: A method of production of glass reaction vessels includes irradiating a laser beam of a wavelength for which a first glass plate is transparent onto the surface of the first glass plate. The first hiss plate is etched. Etching of the first glass plate is terminated when the recesses extend, over only a portion of the thickness of the first glass plate and therefore the recesses have a bottom formed in the first glass plate as a single piece.

  • Publication number: 20220089478
    Abstract: A process for the production of a glass-plastic connection which is form-fitting, and to a form-fitting composite between glass and plastic which is obtainable by the process. The process and the glass-plastic composite are characterized in that a glass, which in particular is planar, neither during the process nor in the glass-plastic composite is subjected to a mechanical load which could lead to cracks, e.g. microcracks. Accordingly, in the composite, the glass is connected to a plastic in a stress-free manner The composite of glass with plastic is especially gas-proof and/or liquid-proof.

  • Patent number: 11156774
    Abstract: An optical component, in particular a passive component, for optical waveguiding, includes: optical waveguides formed in a carrier substrate as a waveguide pattern. The optical waveguides are formed in the carrier substrate by recesses by cutting out the optical waveguide. In an embodiment, the optical waveguide is connected to the carrier substrate by web-shaped supporting structures.

  • Publication number: 20170021450
    Abstract: A method and device for laser machining a substrate, involves deflecting the laser radiation using a galvanometer scanner and an electro-optical deflector. The laser radiation thus deflected multiple times is then directed at a machining position on the substrate. By superposing an additional beam deflection by the electro-optical deflector onto the advance movement in the machining direction, which deflector is operated with steady oscillation excitation for this purpose, the resultant beam deflection follows a circular revolving path. In the process, the series of pulses of a pulsed radiation source is restricted to individual or a plurality of machining positions on the substrate, and forms for example a cutting front so as to thus quickly and reliably produce a kerf having the desired width.

  • Publication number: 20080028792
    Abstract: A method for manufacturing an optical component in which an optical function of the component is created for electromagnetic radiation in an application wavelength range, using laser machining with laser radiation in a machining wavelength range, characterized in that the following steps are carried out: 1) A solid body is provided that is made from a material that in the raw state absorbs the laser radiation in the machining wavelength range, 2) Laser machining is carried out on the solid body employing one or more machining steps and 3) The material of the solid body is transformed into a final state in which the solid body is transparent to the electromagnetic radiation in the application wavelength range and thus fulfills the intended optical function.
