Method of manufacturing a collection of separate variable focus lenses

Abstract

A method of manufacturing a collection of variable focus lenses comprising two electrodes () and a fluid chamber filled with two fluids which are separated by a meniscus, wherein the shape of the meniscus is variable under the influence of a voltage, comprises the following steps: providing an electrically insulating body () having a plurality of through-holes (); applying electrically conducting material to a surface of the body () in order to obtain the electrodes (); covering at least one of the obtained electrodes () by a layer of electrically insulating material; covering an inner surface of a part of the through-holes () with a hydrophobic material; partially sealing these through-holes (); arranging the fluids inside the partially sealed through-holes (); completely sealing the through-holes (); and dividing the body () into portions, such that each portion constitutes a complete lens.
