1. A coordinate measuring machine for measuring coordinates or properties of a workpiece, the coordinate measuring machine comprising:
an extended stylus including an extension element, a probing contact element, and a connection element, wherein the extension element includes:
a carrier portion mounted at the connection element so that the carrier portion is rotatable about an axis of rotation relative to the connection element, and
on a side remote from the connection element, a shaft portion that is aligned so as to deviate from the axis of rotation, wherein the probing contact element is arranged at an end of the shaft portion and lies on the axis of rotation and wherein the carrier portion and the shaft portion are fixedly connected to each other; and
a measurement head to which the extended stylus is attached,
wherein the measurement head is configured to measure deflections of the extended stylus resulting from contacts of the extended stylus to the workpiece.
