Abstract
Refractive indexes of oxide glasses: silica, borate, silicate, aluminate, germanate, tellurite, antimonate and heavy metal gallate are measured in the wavelength range of 0.40–5.03 μm. The zero material dispersion wavelength (ZMDW) was determined using the refractive index data. To predict the ZMDW, we calculated the molecular electronic polarizability, α i , of oxide glasses using the Lorentz-Lorenz equation. An empirical equation between ZMDW and α i was obtained, from which the ZMDW from the compositional parameter, α i can be calculated.
