Abstract

Abstract : UV-curable polymer lenses with a nanolens array decorated on the bottom surface via irreversible electrowetting on a hydrophobic colloidal monolayer. Abstract : Combination of high transmittance and controllable focal length for plano-convex lenses is critical for various optical systems but has been a challenge. Here we demonstrate a strategy to overcome this challenge by introducing the electrowetting of a UV-curable polymeric material on a colloidal monolayer into the formation of plano-convex lenses.
