  • Laser scanning microscope
    Patent number: 6631226
    Abstract: An arrangement and corresponding method are provided for coupling radiation, preferably laser radiation, into a scanning head with a scanning unit in at least two dimensions. The radiation is focussed on an object via a microscope objective via at least one light-conducting fiber which is coupled with the scanning head. A collimator is arranged downstream of the fiber end at the scanning head for collimating the radiation exiting in a divergent manner at the fiber end.
    Type: Grant
    Filed: October 2, 2000
    Date of Patent: October 7, 2003
    Assignee: Carl Zeiss Jena GmbH
    Inventors: Guenter Schoeppe, Stefan Wilhelm, Ulrich Simon, Hartmut Heinz, Bernhard Groebler

  • Arrangement for projecting a test pattern onto a surface to be investigated
    Patent number: 5493400
    Abstract: An arrangement generates a projection beam path on the projection objective outside of the optical axis. This is achieved by mounting an optically transparent wedge forward or rearward of the test pattern. The wedge can be rotated with respect to its orientation by 180.degree..

  • Achromatic phase retarder arrangement
    Patent number: 4930878
    Abstract: An achromatic phase retarder comprises at least one prismatic body with two total reflection surfaces. The light entry surface forms an angle of incidence .alpha., which is different from 90.degree., with the direction of incidence of a light beam, and a first total reflection surface forms a defined angle .phi. with the light entry surface.
