Optical position measuring device |
摘要 |
An optical position measuring device, in particular for a drive for precise positioning, is recited, which comprises two drive units which are movable in respect to each other, wherein one of the two drive units has a graduation as an integral component. The latter can be scanned by a scanning unit connected with the other drive unit for generating position-dependent output signals. The graduation is directly or indirectly disposed on a level surface of the drive unit, from which a distance between the two drive units is created in such a way that by the cooperation of the two drive units the generation of a defined relative movement between the two drive units is possible.
