Abstract
A position-measuring device includes a light source, a first grating, a second grating and photodetectors, light from the light source, which is split into partial beams of different directions at the first and second grating, being directed via a deflecting element to the detector. The deflecting element for incident partial beams having different directions has different regions, so that all partial beams directed from the deflecting element to the detector are approximately parallel.
