Diffractive optics five a means of decreasing the number of components in infrared devices, while meeting the current performances of conventional designs. The testing of such lenses needs two steps: the first one deals with MTF evaluations. The corresponding measurement tool will be briefly presented. An optical bench dedicated to diffraction efficiencies assessments for hybrid lenses is described: the main principles are addressed including the tolerance budget of such a means and experimental results are sketched out.
