Abstract
A lens assembly includes a tube in which optical elements such as lenses or micro-lenses are individually fabricated by dispensing a volume of curable optical polymer into the tube, forming the desired shape for the optical element using one or more plungers having heads corresponding to a desired lensing curvature, applying radiant energy to the tube with the plungers in place to cure the optical polymer, and repeating as needed until the desired number of optical elements are fabricated within the lens assembly which may then be integrated as a single piece into a mobile or wearable device.
