Optical position-measuring device
An optical position-measuring device is arranged for recording the relative position of a scanning unit and a scale movable to it in at least one measuring direction. The scale is configured as a combined unit which includes at least one reflector element as well as a measuring graduation. A light source and one or more detector elements are assigned to the scanning unit. The scanning unit includes splitting device(s) which split the beam of rays, emitted by the light source, into at least two partial beams of rays in the measuring direction, which after being split, propagate in the direction of the scale.
