An optical element comprising: a first monomer polymerized while in the presence of a second monomer to form a first polymer intermixed with the second monomer, the first polymer having a spatially varying degree of cure that provides a predetermined refractive index profile; and the second monomer polymerized in the presence of the first polymer to form a second polymer intermixed with the first polymer, the second polymer stabilizing the refractive index profile.

Optical element for stabilizing refractive index profiles using polymer mixtures

An optical element includes a first lens; a cover; and a cured matrix polymer sandwiched between the first lens and the cover; the matrix polymer, prior to curing, having a monomer mixture dispersed therein; the matrix polymer being selected from the group consisting of polyester, polystyrene, polyacrylate, thiol-cured epoxy polymer, thiol-cured isocyanate polymer, and mixtures thereof; and the monomer mixture comprising a thiol monomer and at least one second monomer selected from the group consisting of ene monomer and yne monomer.

Monomers and polymers for optical elements

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.

Method for stabilizing refractive index profiles using polymer mixtures

Compositions comprising a matrix polymer and a mixture of monomers are used for making polymer mixtures containing the matrix polymer and a second polymer formed from the monomer mixture. Preferably, the matrix polymer comprises a polyester, polystyrene, polyacrylate, thiol-cured epoxy polymer, thiol-cured isocyanate polymer, or mixtures thereof. Preferably, the monomer mixture comprises a thiol monomer and at least one second monomer selected from the group consisting of ene monomer and yne monomer. The compositions may be used to fabricate optical elements such as lenses.
