EMPIR project ‘Reference algorithms and metrology on aspherical and freeform lenses’ (15SIB01, FreeFORM) is working to develop new measurement capabilities to routinely measure aspherical and freeform optical surfaces at a precision of less than 30 nanometres. These surfaces are used in a variety of optical systems, from medical imaging to astronomy.
The project organised a special interest group meeting at euspen on "Structured and freeform lenses". The European Society for Precision Engineering and Nanotechnology (euspen) is an influential community linking industrialists, researchers, respected authorities, new, and established players worldwide. It provides an entrepreneurial platform that enables companies and research institutes to promote their latest technology developments, products, and services and keep up to date with those in the field.
