Patent ID: 8546745

Claim:
An optoelectronic position measuring device, comprising: a code carrier, having at least one optically detectable position code; a radiation source for emitting optical radiation; and at least one detecting element with sensor points for receiving at least a portion of the optical radiation, as a result of which a signal dependent on the position code can be generated, and therefore a position of the code carrier relative to the detecting element can be detected, wherein: the code carrier being movable relative to the detecting element with one degree of freedom; the radiation source and the code carrier being arranged and designed in such a way that the optical radiation is coupled into the code carrier and is guided up to the position code at least partially in a beam path, in the interior of the code carrier, lying in the plane of extent of the code carrier, and is guided onto the detecting element by being decoupled in a decoupling zone; and the decoupling of the optical radiation is performed so that the detecting element is illuminated at a substantially homogeneous intensity distribution.
