Description: The paper outlines a novel concept on the construction of high resolution objectives. Although similar to binary optics technology, this approach brings additional degrees of freedom to the optical design as far as achieving a finer balance of phase curvature via both refractive properties and relative thickness of the multilayer stack. The differential coating objective can be used in conjunction with diffractive surfaces to optimize the transmission efficiency and control the secondary spectrum correction .The basic equations describing the monochromatic and three-color achromat predesign are presented.
