Abstract

A method includes applying a polymer to a mold, the mold having microstructures with the polymer flowing into the microstructures when applied to the mold. The method includes pressing an inorganic substrate onto the polymer. The method includes curing the polymer to fix the polymer to the inorganic substrate to form an optical element from the polymer and the inorganic substrate, the optical element having microstructures formed by the microstructures in the mold. The method includes releasing the optical element from the mold.
