Abstract:
An optical position-measuring device for sensing a position of two relatively movable objects includes a scale connected to one object and having a measuring graduation. A scanning unit is disposed on the other object and has optical elements. An arrangement and design of the optical elements of the scanning unit results in a scanning beam path in which split and subsequently interfered sub-beams propagate mirror-symmetrically with respect to a plane of symmetry and either impinge on and/or are reflected back from the scale in a V-shape. The plane of symmetry is tilted by a defined tilt angle relative to the scale about an axis of rotation that is oriented parallel to a surface of the scale and extends perpendicular to the graduation direction. The sub-beams that are interfered are deflected at the measuring graduation into symmetric diffraction orders. The sub-beams travel identical optical path lengths between splitting and recombination.

Claim (Index 2):
The optical position-measuring device as recited in  claim 1 , wherein sub-beams resulting from the +1 st  and \u22121 st  diffraction orders at the measuring graduation are interfered.
