| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a method for forming a diffractive lens structure.SOLUTION: The method comprises the steps of providing a mold plate, patterning a set of rings arrayed across the mold plate, opening spaces between the rings so that the rings become an in-situ mask on the mold plate, directing an optical polymer into the spaces between the rings, polymerizing the optical polymer to form an array of ring lenses, and transferring the array of ring lenses to a substrate. |
