The ordinary and the extraordinary complex refractive index of PbWO4together with the crystal optical axis orientation are determined on the basis of transmittance and reflectance measurements at normal incidence with polarised light and the measurement of the separation angle between the ordinary and the extraordinary ray at various laser wavelengths. The real part of the extraordinary complex refractive index is lower than the ordinary one (i.e. PbWO4is a negative uniaxial crystal) and they seem not to be affected by a 30 ppm Nb5+doping.
