HOLOGRAM AND METHOD OF MANUFACTURING AN OPTICAL ELEMENT USING A HOLOGRAM
摘要:
A method of manufacturing an optical element (5) comprises testing an optical surface (3) of the optical element, using an interferometer Ia directing measuring light (23a) onto the optical surface wherein the measuring light traverses two successive holograms (44, 48) disposed in the beam path of the measuring light upstream of the optical surface.
