Abstract: A method and device for geometrically determining features of a workpiece, having an image processing sensor having a first beam path, the first beam path comprising at least one front optical unit facing the workpiece to be measured, and an optical splitter being mounted on the side of the front optical unit facing away from the workpiece. The optical splitter connects a second beam path to the image processing beam path, a common beam path being formed, and the second beam path being associated with a second optical sensor, the image processing sensor and the second sensor being designed to directly measure the surface of the workpiece. The front optical unit is formed as a sphere and/or has a longitudinal chromatic aberration.

Abstract: The invention relates to a method for the measurement of workpiece geometries with a coordinate measuring device (10) and to the device itself. According to the invention, measuring tasks may be optimally carried out without a requirement for devices of differing types, whereby one or more sensors (30), which are of optimal application for the relevant measuring task, are used.

Abstract: The invention relates to a method and arrangement for determining structures and/or geometry of a workpiece in a coordinate measuring machine by means of a tactile-optical measuring method, wherein the position of a shaped probe element is determined in at least one direction by means of a first sensor using an optically lateral measuring method, and the position of the shaped probe element is determined in at least one second direction using at least one distance sensor. In order to allow the error-free detection of the shaped probe element using the sensors, the invention proposes that at least one flexible connector element is used in a mounting for fastening the shaped probe element, permeated by the beam path of the first sensor in the beam direction, wherein the connecting element is transparent and/or is disposed severely out of focus with respect to the first sensor.

Abstract: A method for measuring the spatial position and/or opening such as a bore of a work piece by means of a transmitted light process using at least one optical sensor, in a manner which has high precision and is simple. At least two parallel sections between the light cone emerging from the opening and at least two working planes are measured by optical sensors, and the axial direction of the opening is calculated using straight lines which extend between the mid-points of the curves determined thereby.
