A series of TiO2 flint glasses has been developed for producing GRIN glass by ion exchange. Both positive and negative axial and radial gradients were fabricated in high index glasses by exchange of Li+ for Na+ and Na+ for Li+, respectively. Index changes to 0.05 and depths up to 6 mm were achieved and a wide variety of index profiles are shown.
