TNO, TU/e and NMi VSL have developed the NANOMEFOS measurement machine, This machine is capable of fast, universal and non-contact measurement of freeform optics up to 500 mm diameter, with an uncertainty of 30 nm. The optic is placed on a continuously rotating spindle, while a specially developed long range optical probe is positioned over it by a motion system. A separate metrology system measures probe and product position. Measurements of a tilted flat show a reproducibility of 2-4 nm rms. More complex artifacts are measured, and further calibrations are shown to demonstrate the nanometer level measurement uncertainty.
