Fabrication of Lenses by Droplet Formation on a Pre-Heated Surface

A lithography-free, mold-free, single-step method of fabricating high quality optical lenses by curing polydimethylsiloxane (PDMS) droplets on a pre-heated smooth surface allows lenses with different focal lengths to be made by varying the droplet volume and surface temperature.
