A modular scanning unit for a position measuring system and including a support having a recess with a guide surface and a holder adjustably supported upon the support, wherein the holder has a light source and a beam-shaping device aligned with the light source. A scanning plate aligned with the light source and the beam-shaping device. The holder is guided upon the guide surface, displaceable in a first direction and rotatable in all directions, and the holder rests against the guide surface at at least one point, and that, following adjustment, the holder is fixed in place at the at least one point.
