Abstract: The disclosure relates to a transfer stage for moving an object in a vacuum chamber in at least a plane of movement, including at least a first and a second rod each having a first and a second end, the first and second rod being connected one to the other with their first ends by a first hinge, the second end of the first rod being provided with a first hinged support and the second end of the second rod being provided with a second hinged support, the first and second hinged supports being roller supports and the first hinge being provided with a short stroke stage for the object. Particularly when using this transfer stage in lithography systems fast and reliable movements are possible.

Abstract: A method for measuring a contour variation of a measuring area on an object. The method includes the steps of: irradiating the measuring area with a light beam, wherein reflection or transmission of the beam occurs; splitting the transmitted or reflected beam; combining the split beams with each other and observing a fringe pattern representing a differential phase between the split beams; varying the phase of the split beams relative to each other, such that the differential phase is kept within the range of 2 pi; calculating an optical path length difference from the differential phase; and relating the optical path length difference to the contour variation of the object.
