ABSTRACT:
An optical arrangement or length- or angle-measuring device comprising an illumination device for generating partial ray beams and an image lens to receive and transmit the partial ray beams, wherein each of the received partial ray beams defines an angle of inclination with respect to the image lens. The optical arrangement further comprises a plurality of detectors to receive the transmitted partial ray beams and the detectors are positioned so that the distance between the image lens and the individual photodetectors is a function of the angle of inclination of the partial ray beams received by the image lens.
