Hello Everyone,
We selected the company PowerPhotonic and did a Brainstorming Session about Freeform Optics and their applications. 
A BIG Thank You for all the participants, it was a Fun event! And of course thank you for DIY-Optics for organizing it. 
I’m posting here the results for discussion. It could be interesting for anyone who is interested in Optics and Photonics. A lot of wild ideas but I’m sure some of them have an innovation potential, using the manufacturing technology of PowerPhotonic.
All the best,
Daniel
