The intrinsic absorption edge of TeO2 was measured between RT and 20 K for the ordinary ray. A special statistical model was developed for fitting the experimental data. In this way a correct decision function was used avoiding the ad hoc separation of the Urbach equation. The obtained Urbach parameters are Eo=4.254-4.257 eV;h{combining short stroke overlay}ω0 = 2.273 -2.275 × 10-2 eV, σSO = 0.632-0.635. The effectiveness of the method was demonstrated and the reliability of the parameters obtained was discussed.
