Patent ID: 8913234

Claim:
A method for measuring positions of centres of curvature of optical surfaces of a multi-lens optical system, comprising the following steps: a) provisionally determining an optical axis of the optical system using an optical angle-measuring device; b) orienting the optical system and an interferometer with respect to one another in such a way that the optical axis provisionally determined in step a) is aligned with a reference axis; c) measuring spacings between the optical surfaces along the reference axis using the interferometer; d) measuring the positions of the centres of curvature of the optical surfaces using the optical angle-measuring device, wherein in the course of a measurement of the centre of curvature of an optical surface situated within the optical system the measured positions of the centres of curvature of the optical surfaces situated between this optical surface and the optical angle-measuring device and the spacings between the optical surfaces measured in step c) are taken into consideration computationally.
