EUSPEN Structured and freeform surfaces, Paris, November 2018

UPOB Asphere metrology on joint investigations, Braunschweig, February 2019

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 consortium are organising two events where outcomes from the project will be presented:

• EUSPEN Special Interest Group Meeting: Structured and Freeform Surfaces, Paris, 27 - 29 November 2018.
• UPOB 9th High Level Expert Meeting - Asphere metrology on joint investigations, PTB Braunschweig, 28 February - 1 March 2019. This meeting will concentrate on the presentation of measurement results of current lenses, discussion and dissemination of new developments and recent scientific results in asphere and freeform metrology for reflective and transmissive surfaces. 

In addition, outcomes of the project are presented in a paper entitled Hierarchical-information-based characterization of multiscale structured surfaces, published in online journal Science Direct.

This EMPIR project is co-funded by the European Union's Horizon 2020 research and innovation programme and the EMPIR Participating States.
