  • Patent number: 11353681
    Abstract: An objective lens mount and a connection device are releasably connected. The connection device is part of an objective lens or an adapter. The objective lens mount has at least one abutment surface that cooperates with at least one counter abutment surface at the connection device. At least two V-shaped first positioning bodies with at least one positioning surface are arranged such that the positioning surfaces face the longitudinal axis. At least one counter positioning surface at the connection device abuts the positioning surfaces of the objective lens mount. The relative position in the circumferential direction is defined via a rotation stop of the objective lens mount that cooperates with a counter rotation stop of the connection device. A locking device retains the connection device at the objective lens mount and effects a force component in the axial direction and preferably a force component in circumferential direction.

  • Patent number: 10866082
    Abstract: A method for adjusting a measuring device having an interferometer unit with an optical axis, an optical distance measuring device with a measuring axis and a support slide that is moveable along a slide axis. The measuring axis is first aligned parallel to the slide axis. An adjustment body with a first spherical reflection and/or diffraction surface and a retro reflector at the back side is arranged at the support slide. It is brought into a first confocal position, in which a first center point of the first spherical reflection/diffraction surface coincides with the focus of the spherical wavefront that is emitted from the interferometer unit. The retro reflector defines a vertex that is located close to the first center point, such that the measuring axis of the distance measuring device extends close to the focus of the emitted spherical wavefront. In doing so, Abbe-faults can be reduced or eliminated.

  • Patent number: 10031311
    Abstract: The invention relates to a holding apparatus for an optical measurement device. The holding apparatus has two holding units for two preferably telecentric optics units of the measurement device. Each holding unit has a first bearing device and a second bearing device. The two bearing devices are arranged at a distance from one another in the direction of an optical axis of the optics unit. A three-point bearing by three bearing elements for the associated optics unit is provided on each bearing device. At least two of the bearing elements can be positioned along a relevant adjustment axis. The adjustment axes extend substantially at right angles to the relevant optical axis. The optics unit can thus be displaced in a plane spanned by the adjustment axes and can be inclined or tilted on account of the two bearing devices distanced from one another.

  • Patent number: 9505438
    Abstract: An axle support for a motor vehicle includes at least one first support and at least one second support fitted onto the first support. A cavity between the first and second supports that is defined by the surfaces of the supports and circumferential sealing rings is filled with adhesive to adhere the supports to one another. One of the supports is preferably made of metal, preferably cast aluminum, and the other support is preferably made of fiber-reinforced plastic.
