The goal of this work was to investigate the influence of rare-earth ions such as Nd^{3+} and Er^{3+} on the optical properties of tellurite glass of the TeO_2-WO_3-PbO-La_2O_3 system. The optical studies of the glasses comprised spectrophotometry (reflectance and transmittance) and spectroscopic ellipsometry. The spectrophotometric measurements yield a number of narrow absorption bands which correspond to characteristic transitions between the ground- and consecutive excited states of rare-earth ions. From ellipsometric studies, in turn, the dispersion of the refraction coefficient has been obtained which appears to be practically the same for the tellurite glass matrix and the matrix doped with Nd^{3+} and Er^{3+} ions.
