摘要： A fiber-optic point probe for a distance measurement system has an optical fiber that can be connected to a light source or an evaluation device. Illumination light is transmitted via the optical fiber to a beam-forming element and is converted into beam-formed illumination light. The beam-formed illumination light is guided along a first optical axis to a planar surface of a deflection element and is reflected thereby. The beam-formed illumination light reflected on the planar surface spreads along a second optical axis, exits on a spherical end surface of the deflection element and forms a focused illumination beam having a focus area outside of the deflection element. An object surface arranged in the focus area can be probed such that a distance relative to a probe internal reference surface can be determined in a contactless manner.

摘要： 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.

摘要： An inductive rotary transmitter includes a rotor and a stator, which form a rotary transmitter. A rotor winding is arranged on the rotor, and a stator winding is arranged on the stator. Apart from the rotor winding, the rotor does not have any ferromagnetic or soft-magnetic material parts for inductive coupling to the stator or the stator winding. The annularly closed magnetic field lines for inductive coupling are formed on the stator side via the stator winding and a plurality of separate stator elements, which are produced from ferromagnetic or soft-magnetic material. The stator elements overlap both the rotor winding and the stator winding at a respective mounting point of the stator element and direct the magnetic field lines (M) around the rotor winding and around the stator winding to effect a magnetic coupling.

摘要： The invention relates to a measuring device (10) and a method for operation thereof. The measuring device (10) has two measuring units (12), (13), each having a probe unit (16), (35). Each probe unit has a probe element (18), (37). Each probe element (18), (37) has, in a probing direction (x), an outer probe side (18a) or (37a) and an inner probe side (18i) or (37i) opposite the outer probe side. In order to determine a zero position or a reference plane (B) at right angles to the probing direction (x), the two probe elements can be brought into contact via their respective outer probe sides (18a), (37a) or their respective inner probe sides (18i, (37i). As soon as one of the two probe units (16) or (35) detects the contact between the associated probe sides (18a), (37a) or (18i), (37i), a reference plane (B) is defined as zero position in the probing direction (x) by means of the point of contact between the two probe elements. The zero position can thus be determined easily and precisely without calibrated standards or block gauges.

摘要： A metrological apparatus (15) is disposed for adjustment of an attitude of a workpiece (16) having an arcuate upper surface (17) relative to a rotary axis (C) of the metrological apparatus (15). The workpiece (16) is brought into a first rotary position (c1). A plurality of measured points within a measuring plane on the upper surface (17) is recorded. The workpiece (16) is moved into a further rotary position (c2) about the rotary axis (C), and again measured points in the measuring plane (E) on the upper surface (17) of the workpiece (16) are recorded. Based on these recorded measured points, the actual attitude (Li) of the workpiece (16) deviation from a specified target attitude (Ls) are determined. Adjustment parameters are determined, and an adjustment assembly (24) of the metrological apparatus (15) is activated as a function of the calculated adjustment parameters to adjust the workpiece (16).

摘要： A probe unit and a holder of a measurement apparatus that can be releasably connected to one another, particularly without tools, are disclosed. The probe unit includes a mounting device having a contact surface and the holder comprises a counter-contact surface assigned to the contact surface. The contact surface can be divided into multiple separate surface sections that respectively abut along a line or two-dimensionally against the assigned counter-contact surface, if the mounting device takes a contact position. The holding force is produced by at least one mounting magnet of the mounting device and/or at least one holding magnet of the holder. Thereby a magnetic axial force in an axial direction as well as a magnetic circumferential force in a circumferential direction around the axial direction is created, so that the mounting device and holder are urged relative to one another in a desired rotational position in the circumferential direction.

摘要： A measuring system (15) includes a measuring arm receiving unit (18) mounted on the housing (49) or on an axial pin (30) connected to the housing (49) for conjoint rotation so as to be rotatable or pivotable about the axis of rotation (D). A measuring arm (16) can be arranged on the measuring arm receiving unit (18). A motor unit (24) generates a motor torque about the axis of rotation (D) on the measuring arm receiving unit (18). A rotary angle specifying the rotary angle position of the measuring arm receiving unit (18) about the axis of rotation (D) is detected by a measuring device (67) having a scale part (68) and a detection unit (69). The scale part (68) is arranged in the form of a circular arc, annularly, or in the form of a disc about or coaxially with the axis of rotation (D).

摘要： 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.

摘要： 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.
