COORDINATE MEASURING MACHINE WITH WHITE LIGHT SENSOR
First Claim
1. Coordinate measuring machine for measuring a measurement object, comprising a workpiece support for supporting the measurement object and a measuring head carrying an optical sensor, wherein the measuring head and the workpiece support are movable relative to one another, wherein the optical sensor has a objective and a camera, which is designed to capture an image of the measurement object through the objective, wherein the objective has a light entrance opening and a light exit opening, wherein the objective has a multitude of lens-element groups which are arranged in the objective between the light entrance opening and the light exit opening one behind another along a longitudinal axis of the objective, and wherein a first lens-element group from the multitude of lens-element groups is arranged in a stationary fashion in the region of the light entrance opening, wherein there is a clearance in the objective between the first and a second lens-element group, and wherein the coordinate measuring machine furthermore comprises a white light sensor and an at least partly reflective coupling element for coupling the white light sensor into the objective, said coupling element selectively being movable into the clearance.

Abstract
A coordinate measuring machine for measuring a measurement object, comprising a workpiece support for supporting the measurement object and a measuring head carrying an optical sensor. The measuring head and the workpiece support are movable relative to one another. The optical sensor has an objective and a camera for capturing an image of the measurement object. The objective has a light entrance opening and a light exit opening, and comprises a multitude of lens-element groups arranged in the objective between the light entrance opening and the light exit opening one behind another along a longitudinal axis of the objective. A clearance is provided in the objective between the first and second lens-element groups. The coordinate measuring machine furthermore has a white light sensor and a partly reflective coupling element that is selectively moveable into the clearance for coupling the white light sensor into the objective.
