    摘要: A method of manufacturing an optical system comprises assembling an optical element on a mounting frame thereof. The mounting frame is disposed on a rotary table having an axis of rotation, and the mounting frame is adjusted such that a predefined axis of symmetry thereof is parallel to the axis of rotation. The optical element is placed on the mounting frame, and an interferometric measurement of a surface of the optical element is performed. The interferometric measurement is analyzed to arrange the optical element relative to the mounting frame such that a predefined axis of the optical element is parallel to the axis of rotation.

    摘要: A method of manufacturing an optical element includes testing the optical element by using an interferometer optics generating a beam of measuring light illuminating only a sub-aperture of the tested optical element. The interferometer optics comprises a hologram. Results of the sub-aperture measurement are stitched together to obtain a measuring result with respect to the full surface of the optical element. Further, a method of calibrating the interferometer optics includes performing an interferometric measurement using a calibrating optics having a hologram covering only a sub-aperture of the full cross section of the beam of measuring light generated by the interferometer optics and stitching together the sub-aperture measurements to obtain a result indicative for the full cross section of the interferometer optics.
