The density and the refractive index for various compositions of heavy metal fluoride (HMF) glasses, used to make low loss optical wave guides, have been measured by standard archimedes method and by using as Pulfrich refractometer respectively. The density as a function of composition is calculated considering the effective volume of the ions contained in the glass to be invariant. The refractive index as a function of composition is also calculated, based on the Lorenz Lorentz equation, by computing the electronic polarizability of HMF glasses. All calculated results are in good agreement with the observed data. 展开更多
