The tandem component is a holographic component which permits generation of a general complex wave front with 100% light efficiency. It consists of two phase-only elements in two Fourier conjugate planes and of a lens. Applications of this component are discussed such as complex wave front reconstruction, beam shaping, and correlation type measurements.
