Abstract: The present invention relates to glass compositions which are eminently suitable for use as core glasses in fiber optic elements. More specifically, the instant invention is concerned with essentially thoria-free glasses in the La2O3-B2O3-Ta2O5Nb2O5 composition field exhibiting an index of refraction (nD) higher than about 1.80 and a coefficient of thermal expansion (0*-300* C.) of between about 60-70 X 10 7/*C.
