Motivated by the study of dark matter phenomena, we have introducedbefore some exact solutions of the Einstein equations with spherical symmetry which have peculiar energy-momentum tensor.We present here the generalization of this work to the realm of spheroidalgeometries. We will describe this geometries and apply them to the studyof weak lensing.e hope, through this type of studies, to give some light to the problem ofsystematic disagreement between mass estimates coming from different techniques.
