Abstract
A method for producing microstructures for use for x-ray lenses using extrusion techniques and a variable focus x-ray lens assembly are provided. An elongated strip of multiple x-ray lenses and cavities of arbitrary cross-section are produced by an extrusion step. A predefined lens profile of the multiple x-ray lenses has, for example, a parabolic profile for x-ray focusing. The elongated strip of multiple cylindrical compound x-ray lenses can be cut into multiple uniform small lengths, for example, 50 mm lengths, and positioned within a support member. Cutting the assembled support member and x-ray lenses at a selected angle provides a variable focus x-ray lens assembly.
