FreeFORM: Reference algorithms and metrology on aspherical and freeform lenses

2016–2019          Strengthening the metrology for optical surfaces

The use of aspheres and freeforms is growing rapidly, because of their unmatched optical performance. Thus, there is an urgent need to strengthen metrology for optical surfaces.

Project develops reference algorithms, and standards as well as traceable metrology for aspherical and freeform optical elements.

MIKES builds an instrument to measure aspherical and freeform elements with a
few tens of nanometre accuracy.
