Abstract:
A touch probe for a coordinate measuring apparatus, comprising:a touch probe chassis adapted to be attached to the coordinate measuring apparatus; a support for a sensing stylus which is mounted on the touch probe chassis so as to be deflectable from a rest position and on which the sensing stylus is mountable for contacting a workpiece; a deflection measuring system for detecting a deflection of the support for the sensing stylus with respect to the touch probe chassis; and an inspection optics separate from the deflection measuring system, for the inspecting of a tip of the sensing stylus and of a region around the tip; wherein at least one of the support for the sensing stylus and the touch probe chassis comprises a transverse support which extends transversely to a direction of extension of the sensing stylus and which is transparent to light in at least a portion thereof and which is disposed in a beam path of the inspection optics.
