Abstract
An x-ray optical device includes an optic and an adjustable aperture that selectively occludes a portion of an x-ray beam. The adjustable aperture may be positioned between the optic and a sample and may be integrated with the optic or located in close proximity to the optic. The adjustable aperture enables a user to easily and effectively adjust the convergence of the x-rays. In doing so, the flux and resolution of the x-ray optical device can be optimized by using an optic having the maximum convergence allowed for all potential measurements, and then selecting a convergence for a particular measurement by adjusting the aperture.
Claims42
An x-ray optical device comprising:
- a two-dimensional optic which conditions x-rays from an x-ray source;
- and
- at least one aperture including a fixed portion and a movable portion that is movable relative to the fixed portion to adjust the convergence of the x-rays by selectively occluding a portion of the x-rays.
An x-ray reflective optic comprising:
- a first optical element defining a first reflective surface;
- a second optical element defining a second reflective surface, the first and second reflective surfaces reflecting x-rays transmitted from an x-ray source;
- and
- at least one aperture coupled to the first optical element and-the second optical element, the aperture including a fixed portion and a movable portion that is movable relative to the fixed portion to adjust the shape of the aperture, the shape of the aperture being adjusted to adjust the convergence of the x-rays by selectively occluding a portion of the x-rays.
An x-ray reflective optic comprising:
- an optical element which conditions an x-ray beam, the optical element defining a near end and a far end;
- and
- an aperture attached to the far end of the optical element, the aperture being adjusted to adjust the convergence of the x-ray beam by selecting a portion of the x-ray beam delivered by the optical element.
