ABSTRACT:
A position measuring system that includes a scale having a measuring graduation extending along a first line and a scanning device. The scanning device includes a light source that transmits light beams that scan the measuring graduation, wherein the measuring graduation generates modified light from the transmitted light beams and a detector unit that receives the modified light from the measuring graduation. A lens arrangement, arranged between the scale and the detector unit, the lens arrangement generating a defined image of the measuring graduation on the, detector unit, wherein the defined image extends along a second line, whose curvature is different from a curvature of the first line.
