Abstract

A light-defocusing plastic rod (LDR) with an antiparabolic refractive-index distribution was prepared by the two-step copolymerization of diethylene glycol bis(allyl carbonate) (CR-39) with phenyl methacrylate or vinyl benzoate. A concave lens function of the representative LDR was demonstrated with the value of chromatic aberration factor.
