An algorithm is presented for assembling tiles into a variable spaced grating, the one-dimensional analogue of Fresnel zone plate. The algorithm supports blazing. The x-ray properties of such a grating, assumed to be constructed form DNA are estimated, leading to the conclusion that thick structures may be useful for intermediate energy x-rays, but that thin structures for soft x-rays are best used as disposible masks. The diffraction of cold, coherent atoms is a plausible application for thin lenses.
