ABSTRACT:
A measuring camera has a camera housing fixed to a rigid frame providing a reference surface against which an objective lens unit is held so that for a plurality of such units, all can have their respective projection centrums located at a fixed position within the housing. The frame has guides on which a sensor, e.g. of the CCD type, is mounted for movement parallel to the optical axis without play.
