  • Publication number: 20110194091
    Abstract: An optical arrangement has a plurality of optical elements capable of transmitting a beam. A partial housing is provided which extends from a surface of an optical element in the direction of the beam emanating from the optical element, or of the beam incident on the optical element, and whose shape is adapted to the shape of the beam. The partial housing is surrounded at least partially by a measurement structure which is mechanically decoupled therefrom. The measurement structure has at least one sensor.

  • Publication number: 20100039629
    Abstract: An illumination system of a microlithographic projection exposure apparatus has a pupil surface and an essentially flat arrangement of desirably individually drivable beam deviating elements for variable illumination of the pupil surface. Each beam deviating element allows deviation of a projection light beam incident on it to be achieved as a function of a control signal applied to the beam deviating element. A measurement illumination instrument directs a measurement light beam, independent of the projection light beams, onto a beam deviating element. A detector instrument records the measurement light beam after deviation by the beam deviating element. An evaluation unit determines the deviation of the projection light beam from measurement signals provided by the detector instrument.
