Height varies quadratically with radial frequency and radius, mediated by gravitational acceleration, (rv)^2/?2g. I'll venture you want a small curvature with a great deal of uniformity, the model also discounts variable viscosity with temperature and bizarre patterns that would appear with inconsistent anything, I suspect you're gonna want a control system, and probably also to shave the tails to acquire a lens compatible with the paraxial model of magnification.
- buescher 4y agoI recall seeing the technique used in the Amateur Scientist column in Scientific American, with epoxy or casting resin. The verdict was the result was "maybe for infrared"... found it: https://optica.machorro.net/Optica/SciAm/LiquidMirror/1994-02-fs.html https://optica.machorro.net/Optica/SciAm/LiquidMirror/1994-0... If you search around, you'll find people have kept trying and have got somewhat better results in the meantime. Fun stuff.
