We present a theoretical study of diffraction gratings with twin grooves, that is, each period of the gratings corresponds to two grooves. By which it can be used to form amplitude and phase diffraction elements. The diffraction patterns of these elements are particularly interesting, due to the behavior of the diffracted orders, as well as the particularities of the envelope and its diffraction efficiency.
