    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.

    摘要: A method of positioning optical elements relative to each other uses an interferometer apparatus comprising a plurality of holograms generating beams of adjustment measuring light which are incident on optical surfaces of the optical elements. Interference patterns generated by superimposing adjustment measuring light of the beams reflected from the surfaces are indicative of positioning errors of the optical elements. The beams of adjustment measuring light may comprise focused beams forming a point focus on the optical surface and beams of light which is orthogonally incident on extended portions on the optical surface.
