The Technology

Various methods are being used for lenses fabrication, however these are effective usually for large-scale fabrication, where the cost and time spent on the initial mold is justified.

Another method is depositing a finite volume of a liquid (e.g. polymer droplet) on a flat surface, and polymerizing it, yet this method is limited to very small sizes. The buoyancy lens fabrication system is comprised of a liquid chamber, an immersion liquid, a lens liquid, and a thin shape-controlling pad. The entire chamber is filled with the immersion liquid of density ρimm. A finite volume of lens liquid of known density ρlen is injected on top of the pad, and by the choice of above-mentioned properties – wets it entirely. The volume of the lens liquid, the shape of the pad, and the density of the immersion liquid determine a unique solution for the shape of the resulting droplet.
