Thanks for the video. I immediately tried it out with some hobby polymer, gylicerin and a uv torch....sort of worked. could you describe what ratio water to salt/gylicerin to start with and how to dial it in to the particular polymer at hand? my polymer is a little sinky, but the lens was smooth. Thanks for any help.

You would need to run some calculations + fine tune with trial and error. Start with the polymers known density. Calculate the ratio of water + glycerin/salt in order to achieve the same density If your polymer is sinking just add more glycerin

What kind of polymer is used for this process?

In the video a UV curable polymer. The method allows for any "lens liquid" so long as it is immiscible in the surrounding liquid and that you can match their densities to achieve neutral buoyancy . We have even had good results with polymers made for hobbyists: www.amazon.com/VidaRosa-Yellowing-Transparency-Ultraviolet-Bracelets/dp/B093GZH9V5

Did you simulate the phenomenon by numerical method (CFD)?
