Is there any community member who have knowledge about stereolithography of a lens ? Machine park very developed and I am looking for a rapid prototyping company who will produce my lens element.
I saw many propellers from ABS stepless and epoxy or acrylic is better material. Is there optical grade sla material also ?
I am after Glatzel Hologon design but I have to develop a genetic software to develop the lens with material and precision of the output.
May be it will be possible to hand polish the lens !
Its really interesting.
