Abstract
Disclosed is a method for the making of microlenses for optical applications (display for example) resulting from the deposition of a liquid on a substrate, the surface of which has been locally modified so as to increase the wetting capacity of the liquid thereon. The substrate may be a polymer and the wetting liquid may be an organic fluid capable of hardening by an adapted treatment.
