Previous work identified a lens design in which a polymer GRIN element was able to simultaneously correct for firstorder color and temperature variations of a glass singlet. This work presents a materials-based theory, rooted in paraxial optics, that explains this correction and identifies relationships among the GRIN and glass materials which must hold for the correction to be effective. This result provides a path for using polymer optics, with their relatively large thermophysical and thermo-optic coefficients, in passively corrected optical systems over significant temperature ranges.
