Patent ID: 8902434

Claim:
A position measuring device, comprising: at least one material measure comprising an optical structure comprised of a plurality of focusing optical elements, the plurality of focusing optical elements arranged in a first track and a second track; a plurality of light receivers arranged at a distance from the at least one material measure, the plurality of light receivers forming at least one first sensor zone and at least one second sensor zone, wherein the first sensor zone is configured to interact with the plurality of focusing optical elements of the first track for producing an incremental signal and wherein the second sensor zone is configured to interact with at least one focusing optical element of the second track for producing an index signal; a light source arranged at a distance from the material measure and from the plurality of light receivers; at least one transparent substrate between the material measure and the plurality of light receivers, wherein the plurality of light receivers are disposed on a side of the transparent substrate opposite the material measure in the form of a thin-film structure comprising a plurality of layers arranged one above another; and a supporting plate comprising a plurality of circuit-board conductors, the transparent substrate and the supporting plate joined together by a Flip-Chip assembly process.
