Abstract: For dynamically shifting a light beam (7) with regard to an optic focussing the light beam to scan an object in a two-dimensional scanning range with the focussed light beam, at least two beam deflectors (26) are connected in series per each direction in which the light beam is to be deflected with regard to the optical axis of the focussing optic. The two beam deflectors deflect the light beam by two deflection angles (31, 32 and 33, 34, respectively) which are dynamically variable independently on each other. The deflection angles (31 to 34) of all beam deflectors (26) are predetermined for each point of the scanning range (35) in such a way that the light beam (7), in scanning the whole two-dimensional scanning range, always runs through the pupil of the optic (4) at essentially the same point.

Abstract: An optical device for combining a first light beam and at least one second light beam includes a first beam splitting device, a second beam splitting device and a position detector. The first beam splitting device splits a first reference beam from the first light beam and a second reference beam from the second light beam. The second beam splitting device splits a third reference beam from the first light beam and a fourth reference beam from the second light beam. The position detector detects respective positions of the reference beams so as to enable a respective propagation direction and/or a respective position of the first and/or second light beams to be adjusted as a function of the detected positions of the reference beams.

Abstract: In adjusting a microscope having at least two objectives for superimposing measuring beams of light in an object space to the end of obtaining an interference pattern and for monitoring the object space, each objective having a focal point, a focal plane and a pupil, auxiliary beams of light which are distinguishable from the measuring beams are directed into the objectives, and the auxiliary beams getting back out of the objectives are superimposed to obtain an auxiliary interference pattern. Further, the auxiliary beams getting back out of the objectives are imaged as spots.
