Zusammenfassung:In accordance with the present invention, a compound refractive lens for focusing, collecting and collimating x-rays comprising N individual unit lenses numbered i=1 through N, with each unit lens substantially aligned along an axis such that the i-th lens has a displacement ti orthogonal to said axis, with said axis located such that the sum of the displacements ti equals zero, and wherein each of said unit lenses comprises a lens material having a refractive index decrement less than 1 at a wavelength less than 100 Angstroms.
