Methods of imaging, focusing and conditioning neutrons

A compound refractive lens for focusing, collecting, collimating and imaging with x-rays comprising N unit lenses numbered i&equals;1 through N unit lenses substantially aligned along an axis such that i-th lens having a displacement t orthogonal to said axis, with said axis located such that the sum of the lens displacements t 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.

Fabrication of unit lenses for compound refractive lenses

In accordance with the present invention, a compound refractive lens for focusing, collecting and collimating x-rays comprising N individual unit lenses numbered i&equals;1 through N, with each unit lens substantially aligned along an axis such that the i-th lens has a displacement t,orthogonal to said axis, with said axis located such that the sum of the displacements t,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.
