The behaviour of fluorine ion in several fluorogermanates was investigated with infrared absorption method. Densities and refractive indices of glasses in the KF-GeO_2 and xCaF_2・(1-x)CaO・SiO_2 systems were also measured. With these results, total equivalent oxygen density and molar refractivity of CaF_2 were calculated in the latter system. It was suggested that alkaline fluoride has the same or a little stronger role as modifier in the glasses than alkaline oxide. Further, Ca-F interionic distance was calculated in the system xCaF_2・(1-x)CaO・SiO_2 by empirical equation of Kordes and it was suggested that fluorine ion in this system has a tendency to become more compressed state with increasing x.
