Polymer optical articles

摘要

Polymeric optical elements and method for making a polymeric optical elements are provided. The method can include forming a solution by dissolving a polymer in a solvent or melting a polymer to form a liquid. The solution can be filtered with a first filter comprising a pore size of 10 microns or less. The solution can be further filtered with a second filter, wherein the second filter comprises sintered metal. A polymeric optical element can then be formed from the solution.
