Title:
OPTICAL ELEMENTS AND METHODS FOR MAKING THEREOF
Document Type and Number:
WIPO Patent Application WO2006029268
Kind Code:
A3
Abstract:
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.
