Measuring probe adapted to be attached to a probe head of a coordinate measuring machine for determination of at least one spatial coordinate of a measurement point on an object to be measured, the measuring probe comprising an optical measuring unit adapted to provide distance measurements of measuring points at the object and a probe interface (21) which provides modular mounting of the measuring probe to a probe head of the coordinate measuring machine and transmission, in particular bidirectional transmission, of optical signals between the probe and the coordinate measuring machine. The probe interface (21) is designed as an integrally formed module providing a reproducible mountability of the measuring probe at the probe head and comprising a one-sided component of a ball bearing comprising at least three recesses or at least three calotte-shaped elevations (23) and a receptacle (22) formed to receive a defined type of probe ferrule (24) with known and precise position and orientation, and having fixedly arranged the probe ferrule (24) according to the precise position and orientation. The component of a ball bearing and the receptacle are formed as one piece.
