<p>A measuring probe includes a suspension module (112) in which a stylus holder (140) is suspended from a housing on a pair of diaphragms (142,144). At least one of the diaphragms is formed with spiral cut-outs whereby the stylus, which is connected at the centre of the diaphragms, is able to move transversely of the axis of the housing as the stylus holder pivots when transverse forces are applied to the stylus tip. A transducer module (110) is releasably supported on the suspension module by a kinematic mounting (116,118) and is retained in position by magnets (120). The transducer module contains optical transducers (200,210,220) for measuring the deflection of the stylus. The stylus (150) carries a curved mirror or Fresnel lens (212) with optical characteristics according to its length. <IMAGE></p> |
