Abstract
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.
