Abstract
Multiple wavelength X-ray dispersive devices and method of forming them are provided which reflect at least two wavelengths of interest at the same or different angles. The devices include a plurality of layer sets formed on one another, each set having at least two units. At least one unit includes at least two layers having a first d spacing and the second unit has at least one layer with a second d spacing. A plurality of one or both of the units can also be provided in each layer set.
