Claim 12:
13. A method for 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 first and second openings that expose portions of the surface of the transparent substrate, wherein respective groups of the second openings laterally encircle respective ones of the first openings;
replicating optical elements onto the exposed portions of the surface of the transparent substrate defined by the first openings, wherein the replicating is performed using a replication tool having a replication material on respective replication surfaces corresponding to optical elements, wherein the replication tool further includes a plurality of spacers, wherein respective groups of the spacers laterally encircle respective ones of the replication surfaces, and wherein, during the replicating, a free-end of each spacer is brought into contact with a respective one of the exposed portions of the surface of the transparent substrate defined by the second openings;
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.
