Vijaya N. V. Raghavan 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).

  • Method of aligning optical elements
    Patent number: 7365925
    Abstract: A method of aligning an optomechanical assembly and an optomechanical assembly are described.
    Type: Grant
    Filed: March 30, 2006
    Date of Patent: April 29, 2008
    Assignee: Agilent Technologies, Inc.
    Inventors: Kenneth J. Wayne, Vijaya N. V. Raghavan
  • Process for the reduction of undesirable outgassing species
    Patent number: 6893721
    Abstract: A method to reduce undesirable outgassing includes bonding at least two optical components with a bonding material and encapsulating the bonding material with a capping material. The capping material inhibits the outgassing of species that would otherwise be emitted from the bonding material to the surrounding. In one example, the bonding material is silicone and the capping material is epoxy.
    Type: Grant

  • Mounting process for outgassing-sensitive optics
    Patent number: 6844419
    Abstract: Optics used in a high vacuum environment are mounted by bonding by use of addition polymerizing material which used in that environment. The suitability for use in the high vacuum environment is achieved by precise control of outgassing of trapped and dissolved gases, including low molecular weight hydrocarbons and amines, and unreacted material from component parts of said addition polymerizing material. A plurality of application quantities of the polymer are prepared in a large batch for use as pre-mixed frozen (PMF) material. The use of the large batch enables more precise control of mixture so that near-stoichiometric proportions of the polymer components are easily achieved.
