Optical elements are made using micro-jet printing methods to precisely control
the type, position and amount of polymer deposited onto a substrate. In preferred
embodiments, the proportions of two or more different polymer compositions are
varied over the course of the deposition process to deposit adjoining polymer pixels
in the form of a film on the substrate surface. The optical properties of each
adjoining polymer pixel can be selected to provide a predetermined optical property,
including a specific value of index of refraction. Preferably, the film has a radially
non-monotonic refractive index profile and/or an angularly non-monotonic refractive
index profile.
