    摘要: An optical system, such as a microlithographic projection exposure apparatus, includes a first optical component, a second optical component, and a measurement arrangement for determining the relative position of the first optical component and the second optical component in six degrees of freedom. The measurement arrangement is adapted to determine the relative position of the first optical component and the second optical component over six different length measurement sections. The length measurement sections extend directly between the first optical component and the second optical component.

    摘要: A positioning device is provided with a spindle and a spindle nut cooperating therewith for the conversion of a rotary motion into a linear motion for a coarse adjustment, and a piezoelectric linear positioning element arranged in series with the spindle and spindle nut for fine adjustment. The piezoelectric linear positioning element is relieved of transverse forces and moments by a cardan joint that is arranged between an object seating and the spindle.

    摘要: The present invention relates to a method for evaluating fringe images, in particular, for topographic measurements. During a first step, several phase-displaced patterns are recorded sequentially in time, and the respective phase relations of these patterns are determined by evaluation in the spatial domain (14a, 14b, 15). During a second step, after the phase shifts have been determined accurately in this manner based on the video images themselves, a pixel-by-pixel evaluation of the phase-displaced pattern is performed in the time domain. The invention also includes computer hardware for performing the evaluation of the strip images in video real time.

    摘要: The present invention is a process by which optical surfaces of lenses, particularly plastic progressive lenses and molding shells for producing lenses are manufactured directly in a single step according to didicidual data. A blank from which an optical surface or a molding shell is to be manufactured is held at the workpiece carrier of a spindle axis (Z axis) of a shaping machine and is directly turned into its final form by a turning tool which can move relative to the blank (in the X axis), i.e., transversely to the direction of displacement of the tool. During each rotation of the spindle, the turning tool is incrementally adjusted towards or away from the blank depending on the characteristic surface data, which may be predetermined or calculated on-line.
