Abstract: A process for measuring of an object geometry is disclosed using a coordinate measuring device wherein the object geometry is recorded by an optical sensor and represented as an image content, wherein within the image content, geometric structures suitable for the measurement of the object are subsequently selected and evaluated.

Abstract: A coordinate measuring device for measuring three-dimensional or two-dimensional objects in the direction of the X, Y and Z axes of the coordinate measuring device. The X and Y measuring axes run in one plane in order to achieve a compact unit and a high measuring accuracy.

Abstract: An arrangement for measuring the geometry or structure of an object by means of a co-ordinate measuring device with an optical system for recording and reproducing a measured point on at least one optical sensor, whereby the optical system has at least one displaceable lens group having at least one measuring lens and at least some of the measuring lenses are supported in a housing. At least one further lens is arranged in at least some of the housings for supporting the measuring lenses of the at least one displaceable lens group, for the focusing of a light beam on the object.

Abstract: A bearing (32) for a coordinate measuring instrument including a slide (36) which can be axially displaced in relation to a fixing device (34) and which can be supported opposite the fixing device by means of at least one air bearing (38, 40). In order to be able to utilize the bearing for all axes of the coordinate measuring instrument while simultaneously using outer surfaces of the slide as mounting surfaces for sensors, the invention provides that a force that works counter to the air bearing can be generated by a magnetic field (42, 44).

Abstract: An illumination arrangement for illuminating an object to be measured, destined in particular for a coordinate measuring system or a measuring microscope, includes several light sources (18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 60, 62, 64, 66, 68) going out from a support (16, 70) having different incidence angles with respect to an optical axis (14) of an optic, by means of which the object can be measured or imaged. The light sources in the support are arranged in such a way, that their incidence angles (?, ?, ?, ?, ?) intersect the optical axis (14) in divergent areas (48, 50, 52, 54, 56).

Abstract: Method for carrying out the non-contact measurement of geometries such as surfaces of objects, with a coordinate measuring machine with a laser beam that is projected onto a measuring point of the object via an optical system, and in which the light that is reflected or scattered by the measuring point is detected by a detector. The optical system includes a zoom lens, whose lens groups each are each motor-adjusted separately from each other in positions for working distance and/or resolution and/or measuring range.

Abstract: The invention relates to a method and an arrangement for determining the geometry of objects using a coordinate measuring device. An optical system (10) is used to form an image of at least one light or scanning spot whose position depends on the geometry of the object on at least one detector (30). The imaging scale, depth of field and distance from the object are adjusted by means of a zoom lens (18) whose lens groups (20, 22) are each power driven and are axially displaceable.

Abstract: The invention relates to a method for determining the deviation in the measured geometric dimensions and/or position of an object from definable desired values of said dimensions and/or position. Before determining the deviations the measurement values of the dimensions and/or position of the object are adapted to the desired values, taking into consideration definable tolerance values of said desired values of the dimensions and/or position of the object.

Abstract: A method for measuring structures of an object using a feeler element associated with a coordinate measuring instrument and extending from an elastic bendable feeler extension is disclosed, and wherein the feeler element is brought into contact with an object having structures to be measured and the position of the feeler is then determined by comparing the position of the feeler as determined by the coordinate measuring instrument with the position determined by the optical sensor.

Abstract: The invention relates to a method and an arrangement for measuring the structure of an object. The structure is scanned by touch, by means of a scanning element whose position is optically detected. The force produced after the contact between the scanning element and the object is determined and optionally adjusted to constant values.

Abstract: The invention relates to a system for securing and/or controlling the final position of a tongue rail (14) that can be adjusted in relation to a rigid rail (12). A catch element extends from said tongue rail and interacts with a lever element in such a manner that in the respective final position of the tongue rail the latter is supported and the position of the tongue rail is measured.

Abstract: A device for measuring structures of an object by means of a stylus (10) assigned to a coordinate measuring device (22) and including a stylus element (12) and a stylus prolongation (14) in the form of an optical waveguide. The coordinate measuring device (22) includes a sensor for the optical determination of the stylus element (12) and/or at least a target marker assigned directly to the stylus element, and an evaluation unit, with which the structure of the object can be- calculated from the position of the optical sensor in relation to the coordinate system of the coordinate measuring device and the position of the stylus element or the target marker, measured directly by means of the optical sensor.
