Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional x-ray mirror optics are limited by their numerical aperture, optical aperture, and focal length, which restricts the collection and focusing of x-rays, particularly from laboratory sources, and can lead to reduced spatial resolution and efficiency in x-ray analysis systems.
Innovation Solution
The development of x-ray mirror optics with a plurality of surface segments having quadric cross-sections with differing parameters, allowing for increased numerical apertures, larger optical apertures, and shorter focal lengths, achieved through the use of non-axially symmetric mirror sections and substrates with specific curved surface shapes, such as hyperbolic and paraboloidal profiles, which are fabricated using advanced techniques like etching and mandrel shaping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional x-ray mirror optics are used, then the structure is simple and easy to manufacture, but the numerical aperture, optical aperture, and focal length are limited, reducing collection efficiency and spatial resolution
Solution Approach 1:
The mirror surface is divided into multiple discrete mirror sections, each with its own support structure. This segmentation allows for complex three-dimensional surface profiles to be achieved while maintaining manufacturability through modular fabrication and assembly processes.
Solution Approach 2:
The invention transitions from conventional two-dimensional mirror surfaces to three-dimensional mirror sections with complex curved profiles. Each mirror section has surface contours in multiple dimensions, enabling enhanced focusing and collection capabilities that overcome the limitations of simple parabolic or elliptical shapes.
2Productivity
If conventional grazing incidence mirrors are used, then the design is simple, but the collection efficiency and numerical aperture are restricted
Solution Approach 1:
The optical system is segmented into multiple mirror sections arranged in sequences (such as nested or cascaded configurations). This allows the system to collect x-rays from a wider angular range and improve numerical aperture while maintaining manageable complexity through modular design.
Solution Approach 2:
Mirror sections are arranged in nested configurations where smaller mirror sections are positioned within the shadow of larger ones. This nesting approach maximizes the optical aperture and collection efficiency by utilizing the three-dimensional space effectively, allowing multiple reflections to contribute to the focused beam.
3Manufacturing precision
If conventional single-reflection mirrors are used, then the optical path is short, but the focusing capability and spatial resolution are reduced
Solution Approach 1:
The optical system is designed to maintain continuous useful action through multiple reflections. Each mirror section contributes to the progressive focusing of x-rays, with each reflection adding to the convergence of the beam. This continuous focusing action across multiple reflections enhances the final focusing precision without requiring excessively long optical paths.
Solution Approach 2:
The system uses three-dimensional mirror surfaces with complex curvature variations in multiple directions. This allows for enhanced focusing power in both horizontal and vertical planes simultaneously, achieving high spatial resolution more compactly than conventional single-plane mirrors would allow.

Function Achieved in This Case
This design enhances the collection and focusing capabilities of x-rays, improving the spatial resolution and collection efficiency, enabling the use of laboratory x-ray sources with lower brightness and accommodating a wider range of x-ray wavelengths without the need for multiple zone plates, thus overcoming the limitations of conventional optics.
Implementation Method 1
Grazing incidence x-ray mirrors are achromatic and can provide an advantage over diffractive and refractive optics for many applications. Generally, the grazing incidence angles for desired reflectivities are equal to or less than the critical angle.

AI summary
An x-ray mirror optic includes a plurality of surface segments with quadric cross-sections having differing quadric parameters. The quadric cross-sections of the surface segments share a common axis and are configured to reflect x-rays in a plurality of reflections along a single optical axis or in a scattering plane defined as containing an incident x-ray and a corresponding reflected x-ray.
