  • High-power discharge lamp
    Patent number: 7759849
    Abstract: A laser excitation lamp has a discharge tube and a hot cathode in the shape of a pin. The gas space is reduced in the region of the pin cathode. A method is also provided for production of the lamp, in which the gas space or the free cross section around the cathode is reduced by another processing step. The laser excitation lamp may be used as a pumping light source for lasing media.
    Type: Grant
    Filed: October 17, 2005
    Date of Patent: July 20, 2010
    Assignee: Heraeus Noblelight Ltd.
    Inventors: Jeremy Woffendin, Uwe Krönert
  • High-pressure discharge lamp
    Patent number: 7489078
    Abstract: A high-pressure discharge lamp has a pressure chamber with two opposite end regions and delimited by a cylindrical envelope made of glass. An electrode is provided at each of the two end regions, the electrodes projecting into the pressure chamber and being arranged in the pressure chamber as anode and cathode. A discharge chamber is formed between the electrodes. The two end regions of the pressure chamber are designed differently at least outside of the discharge chamber.

  • Ultraviolet sensor
    Patent number: 5497004
    Abstract: A UV sensor having a photodetector for measurement of UV radiation, an SiO.sub.2 -containing dispersive element disposed ahead of the photodetector in the direction of incident UV radiation and an optional housing having an entry opening for UV radiation. The dispersive element contains quartz glass with interiorly disposed boundary surfaces, the orientations of which are statistically homogeneously distributed.
