What is the UV-cured polymer? I read a paper [1] by Bercovici, didn't see it identified. [1]https://www.researchgate.net/publication/354978270_Fabrication_of_f

  UV curable liquid optical polymer that you can buy on Amazon ... maybe something like https://www.amazon.com/Upgraded-Ultraviolet-Decoration-Transparent-Activated/dp/B09GXQYC2G/ https://www.amazon.com/Upgraded-Ultraviolet-Decoration-Trans...

In this work, we demonstrate curing of PDMS (Sylgard 184, Dow, MI), and UV adhesive (NOA61, NOA63, NOA81, Norland, NJ) lenses. The PDMS lenses are cured by incubating them at 80 C for 1.5 hr, at 60 C for 4 hr, or at room temperature for 24 hr. The UV adhesive is cured by exposure to light at 365 nm (a 36 W consumer grade nail lamp) for 2-5 min, depending on the thickness of the lens and the specific adhesive chosen. Since both PDMS and Norland adhesives are immiscible in water and have densities between ~1.03 (PDMS) g/mL and ~1.12 g/mL (Norland), the water\glycerol-based immersion liquid allowed us to precisely control the density difference. Since preparation of PDMS involves intense mixing of the base resin with a cross-linker, we degassed the PDMS mixture for 20 minutes before injecting it into the bounding surface, in order to eliminate any bubbles trapped in the fluid due to the mixing.
