Reference algorithms and metrology on aspherical and freeform lenses

Heikkinen, Ville (Manager)

BA6601 Length metrology

Project: EU project

Description

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.

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