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, αi, of oxide glasses using the Lorentz-Lorenz equation. An empirical equation between ZMDW and αi was obtained, from which the ZMDW from the compositional parameter, αi can be calculated.
