发明名称 Method of aligning an optical system
摘要 A method of manufacturing an optical system having plural optical elements mounted relative to each other on a mounting structure of the optical system comprises disposing the optical system in a beam path of an interferometer apparatus having an interferometer optics and a selectable hologram for shaping a beam of measuring light to be incident on surfaces of the optical elements of the optical system; selecting a first hologram of the interferometer apparatus and recording at least one first interference pattern generated by measuring light reflected from a surface of a first optical element; selecting a second hologram of the interferometer apparatus, wherein the second hologram is different from the first hologram, and recording at least one second interference pattern generated by measuring light reflected from a surface of a second optical element, which is different from the first optical element; and adjusting a position of the first optical element relative to the second optical element on the mounting structure based upon the first interference pattern and the second interference pattern.
