In this work we introduce a new category of diffractive lenses called multifocal binary Gabor zone plates (MGZP). These lenses are designed by integrating in a single plate multiple binary Gabor zone plates with distinct harmonic terms. We demonstrate how this binding allows the creation of a desired multifocal distribution that can be customized in the lens design to generate multiple focal points with adjustable focal distances of variable intensity. Numerical examples are presented of a bifocal and to a trifocal lenses with equi-energetic foci.
