Abstract: A camera lens assembly includes a focusing mount having a receiving lug and optical elements, which are arranged in the focusing mount, and define an optical axis. An adapter ring has a first planar surface and a second planar surface which are parallel to each other. The first planar surface is in contact engagement against a camera-side contact surface of the focus mount and the second planar surface is in contact with a lens-side contact surface of a lens mount. The lens mount has a tubular-shaped lens mount socket and lens mount attachment elements which are configured to coact with the camera mount attachment elements of a camera.

Abstract: The camera lens assembly (1) of the invention includes: (1) a focusing mount (2) having: (a) a defined distance from the camera-side contact surface (3) of the focusing mount (2) to the camera image plane (BE) of XAF-BE?57.

Abstract: In order to initiate the operation of an incremental-correction measurement system, which measures such guidance errors as instantaneous lateral offset of a movable machine part with respect to its guidance direction (Y), a reference mark is provided by two cylindrical lenses (4, 5) which are arranged at an angle to each other and to the guidance direction. Since the distance intercepts for Y-direction scanning of and between the two cylindrical lenses is dependent on the instantaneous lateral offset (.DELTA.X) of the guided part, it is possible to determine the absolute offset values (.DELTA.X.sub.1, .DELTA.X.sub.2) of two spaced incremental-correction measurement systems (K1, K2), using pairs of pulses (A.sub.1/2, B.sub.1/2) generated by two signal transmitters (KNIP1, KNIP2) upon their scanning traverse of the respective cylindrical lenses in the course of a single calibration run.
