Method for stabilizing refractive index profiles using polymer mixtures

A method for making an optical element comprises polymerizing a first monomer to form a first polymer, the first polymer having a spatially varying degree of cure that provides a predetermined refractive index profile; and polymerizing a second monomer in the presence of the first polymer to form a...

Summary:A method for making an optical element comprises polymerizing a first monomer to form a first polymer, the first polymer having a spatially varying degree of cure that provides a predetermined refractive index profile; and polymerizing a second monomer in the presence of the first polymer to form a second polymer intermixed with the first polymer, the second polymer stabilizing the first polymer and the refractive index profile.
