PROCESS FOR THE PRODUCTION OF OPTICAL ELEMENTS ABSTRACT OF THE DISCLOSURE A process for the production of optical elements which comprises forming on a substrate a light-sensitive film containing at least a photoreactive compound, and selectively exposing the film to radiation to cause migration of the unreacted compound from an unexposed area to an exposed area by the exposure. The present process is particularly useful in the low-cost mass- production of various micronized optical elements such as plastic microlenses and arrays thereof, optical waveguides, diffraction gratings, and holograms, for example. An optical device comprising the optical elements of the present invention is also disclosed.
