  • Microelectromechanical system for tuning lasers
    Patent number: 9893491
    Abstract: A micromechanically produced optical device includes: a carrier for carrying the micromechanically produced device; a diffraction grating for diffracting light; a plate for carrying the diffraction grating; and deflectors for deflecting the plate in relation to the carrier, the deflectors comprising bearings for movably bearing the plate and a driver for moving the plate; the deflectors being configured for rotational deflection of the plate and for translational deflection of the plate.
    Type: Grant
    Filed: July 29, 2016
    Date of Patent: February 13, 2018
    Assignee: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V.
    Inventors: Harald Schenk, Jan Grahmann, Joachim Wagner, Ralf Ostendorf, Marcel Rattunde

  • Method for verification of particles having a sensor area and sensor arrangement for carrying out this method
    Patent number: 7446870
    Abstract: The invention relates to a method for verification of particles, in particular of nanoparticles (16), in which a sensor area (15) is made available for this purpose, on which the particles can accumulate. The invention also relates to a sensor arrangement having a sensor area (15) which is suitable for carrying out the method mentioned. The invention provides for a plurality of sensor areas (15) to be arranged, on which particles which each have different characteristics can accumulate. For example, this makes it possible to classify nanoparticles (16) of different size, thus advantageously allowing a statement to be made on the size distribution of the nanoparticles (16) in a nanopowder.
