We study the propagation of wavefronts produced through cemented doublet lenses, considering a plane wavefront propagating parallel to the optical axis. We provide formulas for the zero-distance phase front by using Huygens's principle, also we provide formulae to represent the shape of refracted wavefronts propagated arbitrary distances along the optical axis, which are function of all parameters involved in the process of refraction. We present examples of doublet lenses showing the evolution of the wavefronts arbitrary distances, assuming different wavelengths for the refractive indices of the lenses, for this purpose we compare the dispersion effects produced through this particular kind of lenses.
