Patent ID: 7274506

Claim:
A method of 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, the method comprising the steps of: directing auxiliary beams of light which are distinguishable from the measuring beams into the objectives, the auxiliary beams being focused through the objectives into the focal points of the objectives, wherein the auxiliary beams and the measuring beams are distinguishable based on at least one of the following: the auxiliary beams and the measuring beams having different wavelengths; and the measuring beams comprising pulsed beams and the auxiliary beams comprising continuous beams, superimposing the auxiliary beams getting back out of the objectives within a common image of the pupils of the objectives to obtain an auxiliary interference pattern, and additionally imaging the auxiliary beams getting back out of the objectives as spots in a common image of the focal planes of the objectives.
