With Multiphoton Optics‘ Two-Photon Polymerization (TPP), the high-precision production of individual elements with a resolution of down to 100 nm is achieved. This makes it possible to produce metalenses for visible light from polymers. The metalens shown on the title page of Laser Magazin consists of elements from 100 nm to 450 nm width. It was created as part of the PHENOmenon project, which receives funding under funding number 780278 from the European Union's Horizon 2020 research and innovation programme. The PHENOmenon project is an initiative of the Photonics Public Private Partnership.
