Patents by Inventor Ulric B. Ljungblad

Ulric B. Ljungblad has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • High energy, low energy density, radiation-resistant optics used with micro-electromechanical devices
    Patent number: 6891655
    Abstract: The present invention includes methods and devices that improve the radiation-resistance of a movable micromechanical optical element. In particular, a radiation-resistant layer is added to a movable micro-mechanical optical element, suitable to reduce the surface and bulk material changes to the element that result from exposure to pulsed laser energy densities less than 100 micro-joules per square centimeter and at wavelengths less than or equal to about 248 nm.
    Type: Grant
    Filed: January 2, 2003
    Date of Patent: May 10, 2005
    Assignee: Micronic Laser Systems AB
    Inventors: Thomas J. Grebinski, Ulrike A. Dauderstadt, Torbjörn Sandström, Ulric B. Ljungblad, Christian Kunath, Eberhard Kurth
