Embodiment 1
[0032] Reference attached figure 1 , A method for manufacturing a one-dimensional X-ray refractive diffraction microstructure device made of aluminum material. The one-dimensional X-ray refractive diffraction microstructure device is composed of a plurality of lens units in a coaxial order. The lens is composed of the main body of the gap. The upper side wall of the lens is provided with upward stepped steps, and the step width of each step is equal; the lower side wall of the lens is provided with an axis as the center line and the upper side of the lens The steps of the wall are symmetrically arranged downward step-like steps, the lens is provided with the open air gap, the cross-sectional shape of the air gap is elliptical, and the air gap corresponds to the largest diameter size in the minor axis direction of the ellipse The size of the ellipse is smaller than the minor axis of the ellipse, the major axis of the elliptical air gap of the lens is on the same straight line, and ...
Embodiment 2
[0051] In the technical solution of this embodiment, the metal material electroformed cathode film described in step (B) is titanium material, and the thickness of the PMMA coated on the surface of the titanium sheet in step (I) is 500 micrometers, and the remaining steps are the same as in Example 1.
Embodiment 3
[0053] In the technical solution of this embodiment, the metal material electroformed cathode film in step (B) is nickel material, the thickness of PMMA coated on the surface of the titanium sheet in step (I) is 2000 microns, and the remaining steps are the same as in Example 1.
[0054] Process tests have been performed on the above three embodiments, and it can be seen from the test results that they all meet the requirements of the structural shape and size of the X-ray composite lens, and the process test effect of embodiment 2 is the best.
