Dispersion des indices de refraction du molybdate de plomb (PbMoO4) et de la paratellurite (TeO2)

An infrared goniometer, shortly described has been used for the determinations of the refractive indices of two interesting acousto-optical materials: lead molybdate (PbMoO₄) and paratellurite (TeO₂). The given results complete those previously available which concern only the visible range. Coefficients of Sellmeier equations for the whole transparency range of both materials are also given and discussed.
