Abstract: Previous work developed a first-order theory for picking optimal pairs of materials for gradient index (GRIN) achromatic singlets. This work extends that concept to include the addition of a third material to a GRIN blend, to improve performance further. Several ternary-based GRIN lens designs are compared to binary versions. Implications for material development in gradient index optics are discussed.
