    Abstract: An electromagnetic drive system drives the oscillating secondary mirror or wobble mirror of a reflecting telescope. The driving force of the drive system is directly proportional to the current and the drive system is digitally controllable. By incorporating a tachometer generator and a contactless operating position measuring unit, it is possible to select such function curves for the leading and trailing edges of the wobble function which will permit a jolt-free drive of the mirror.

    Abstract: The invention contemplates a method and apparatus for automatically performing digital measurement of vertex dioptric powers in the principal planes of toric spectacle lenses. A spectacle lens is transilluminated by a parallel-ray bundle of monochromatic light which, after passage through the spectacle lens, is limited by an annular stop in the immediate vicinity of the vertex of the spectacle lens. A beamsplitter divides the light which passes through the spectacle lens into two individual light beams. As a result, an elliptical figure is projected to two planes, in each of which is located at least one self-scanning diode line. Diode-line scanning develops intercepts of the projected elliptical figure, and from the positional locations of these intercepts (in relation to the local intercept of the optical axis) a computer performs a selected one of a plurality of evaluation procedures (a) to develop projected-figure reorientation or displacement as necessary to permit it then (b) to perform a desired measurement evaluation. Provision is made for automatic detection of whether a given spectacle lens is or is not within the currently set range of measurement capability and, if determined to be outside such range, the fact of such detection is operative to change optical elements of the apparatus for optimum measurement-range accommodation of the particular spectacle lens.

    Abstract: A probe head for a coordinate measuring machine has a stylus resiliently suspended in a housing. A sensor arrangement serves for detecting deflections of the stylus relative to the housing. The sensor arrangement comprises at least one Hall sensor having a magnet and a Hall element arranged in a vicinity to each other. When the stylus is deflected, the magnet is laterally passed by the Hall element in a direction defined from the North Pole to the South Pole of the magnet or vice versa. A Hall voltage of changing polarity can be tapped at the Hall element then. A preferably linear range around the polarity change is processed in order to determine the deflection of the stylus.

    Abstract: For the adjustment and mounting of an optical component in an optical instrument, the optical component is held by an adjusting device not forming part of the instrument. After the adjusting process is completed, the component is attached to the instrument by a liquid or pasty substance which solidifies with slight change in volume. The optical component or its mount and the instrument are so developed that a form-locked, force-locked, or adherence-locked attachment is produced between them. The adjusting process can be made objective by a position-resolving receiver; the evaluation of the adjustment image and the carrying out of the adjustment movements can be effected by a computer which can also carry out the entire adjustment process completely automatically. After the firm attachment of the optical component to the instrument, the adjusting device is removed.
