Claim 6:
7. A method fort replicating optical elements, the method comprising:
providing a transparent substrate having a structured UV curable shield adhering to its surface, the UV curable shield having openings that expose portions of the surface of the transparent substrate;
replicating optical elements onto the exposed portions of the surface of the transparent substrate using a replication tool having a replication material on respective replication surfaces corresponding to optical elements, wherein the replication tool further includes spacers each of which laterally surrounds a respective one of the replication surfaces, and wherein, during the replicating, a free-end of each spacer is brought into close proximity to a respective one of the exposed portions of the surface of the transparent substrate;
applying UV radiation to the replication material and to the UV curable shield to cure the replication material and the UV curable shield; and
subsequently removing the shield from the transparent substrate.
