Abstract
A method for manufacturing a polymer miniature lens on a substrate with the lens forming pattern, and the liquid polymer is dispensed therein. The lens forming pattern having a periphery area and an interior area, most portion of the periphery area having a property of confining liquid polymer, while the interior area having at least one portion exposing the surface of the substrate; depositing liquid polymer onto the lens forming pattern; and curing the liquid polymer after the liquid polymer reaches equilibrium shape and is confined to the periphery area. The invention also discloses a collimator including the polymer miniature lens.
