Abstract
Methods are disclosed by which two-dimensional and three-dimensional pattern layers may be formed on non-planar surfaces, including optical elements such as lenses with one or more cylindrical, spherical or aspheric surfaces. Patterns with features in the micro- and/or nano-size regime comprised of organic, inorganic or metallic materials may be formed by the methods described herein.

A method for fabricating a pattern on a compound curved surface, said method comprising:
- a. forming a relief pattern on a stretchable surface to form a replication mold,
- b. coating a layer of curable polymer material on said stretchable surface,
- c. causing said coated stretchable surface to come in conformal compliant contact with a curved substrate
- d. exposing said curable polymer material to radiation to cause solidification of said polymer material,
- e. withdrawing said stretchable mold from contact with said substrate so as to leave the solidified polymer having a pattern complementary to that of the relief pattern of the stretchable replication mold as a layer on the surface of said substrate.
A method for fabricating a pattern on a compound curved surface, said method comprising:
- a. forming a relief pattern on a stretchable surface to form a replication mold,
- b. coating a layer of curable polymer material onto the relief pattern of said stretchable replication mold,
- c. solidifying said layer of polymer material,
- d. causing the surface of said solidified polymer layer on said stretchable surface to come into conformal compliant contact with a curved substrate
- e. using an adhesive to adhere said solidified polymer layer to said curved substrate,
- f. separating said stretchable replication mold from said solidified layer of polymer material so as to leave the solidified polymer having a pattern complementary to that of the relief pattern of the stretchable replication mold as a layer on the surface of said substrate.
A method for fabricating a pattern on a compound curved surface, said method comprising:
- a. forming a relief pattern on a stretchable surface,
- b. causing said coated stretchable surface to come in conformal compliant contact with a curved substrate
- c. Using an adhesive to bond the backside of said curable polymer material to a curved substrate.
