molding the base lens against the mold surface; and,

thereby producing a base lens with an array of microlenses molded directly on the front surface of the base lens.

2. The method according to claim 1 , wherein molding the base lens comprises cast molding the base lens.

3. The method according to claim 1 , wherein molding the base lens comprises injection molding the base lens.

4. The method according to claim 1 , wherein the microlenses have the same optical surface geometry as one another.
