Abstract
A compound refractive lens for focusing, collecting, collimating and imaging with x-rays comprising N unit lenses numbered i=1 through N unit lenses substantially aligned along an axis such that i-th lens having a displacement ti orthogonal to said axis, with said axis located such that the sum of the lens displacements ti equals zero, and wherein each of said unit lenses comprises a lens material of lithium, carbon, or polyimide. A method for molding and housing the unit lenses is provided such that the unit lens have high surface and optical quality, and do not chemically deteriorate due to absorption of water or oxidation.
