Measurement of the positions of curvature midpoints of optical areas of a multi-lens optical system

摘要

The method involves calculating the distance between the optical surfaces (S1-S3) of multi-lens optical system (62) along a reference axis (34) using a short-coherence interferometer (24). The position of center of curvatures (K1-K3) of optical surfaces is measured using an optical angle measuremnet device (22), based on the calculated distance of optical surfaces. An independent claim is included for device for measuring position of center of curvature of optical surfaces in multi-lens optical system.
