    摘要: An interferometric device for position measurement of an element moveable in a plane is disclosed. A laser light source measures the position of the moveable element and emits the required measuring light. A beam splitter splits the measuring light into a first partial beam path and a second partial beam path, which each impinge on a reflecting surface of the moveable element via an interferometer. Herein, at least the beam splitter, which splits the measuring light into a first partial beam path and a second partial beam path, and the beam splitter, which directs the third partial beam path onto an etalon via an interferometer, have a respective beam trap associated with them, which traps the light returning from the respective interferometers.
