EMPIR project (15SIB01 FreeFORM) Reference algorithms and metrology on spherical and freeform lenses will develop new measurement capabilities within European National Measurement Institutes to routinely measure higher-performance aspheres and freeform surfaces below 30 nanometres.Results from the project will be presented at the conference. The international conference and exhibition provides a leading forum for industrialists and academics alike to review the best of world-wide industrial innovation, progressive research and technology developments. Delegates will gain an insight into the precision engineering and nanotechnology priorities of Europe’s leading industrial nation.
