Abstract: A scanning sensor system for noncontact optical scanning of object surfaces having a sensor head (2) and an optics unit (3) as system components matched to one another. The optics unit (3) can be attached and positioned with high precision on the sensor head (2) by means of a fixing device (4).

Abstract: A scanning sensor system for noncontact optical scanning of object surfaces having a sensor head (2) and an optics unit (3) as system components matched to one another. The optics unit (3) can be attached and positioned with high precision on the sensor head (2) by means of a fixing device (4). The fixing device (4) has three bearings (20, 21, 22), on which an optics unit (3) pressed against the sensor head (2) is borne and thereby positioned. Each of the three bearings (20, 21, 22) has a pair of bearing parts (17a, 17b; 18a, 18b; 19a, 19b) matched to one another in respect of their shape and positioning, these bearing parts having bearing surfaces in which respectively one of the bearing parts (17a, 18a, 19a) of the bearing part pairs is in contact with at least one bearing surface of the other bearing part (17b, 18b, 19b) of the bearing part pair.
