Needle optimization is widely used in visible and infrared region, but it is rarely utilized in X-ray and extreme ultraviolet waveband. We use Needle optimization to design Pt/C X-ray supermirrors, and the grazing incidence angles are 1.0, 1.4, and 1.7 degree, respectively. A modified target is introduced into optilayer software. A good result is obtained by Optilayer software combined with IMD software. The difference of design results between block method and needle optimization is discussed.

通过针头优化设计Pt / C X射线超级镜

针头优化广泛用于可见光和红外区域，但很少用于X射线和极紫外波段。我们使用Needle优化来设计Pt / C X射线超级镜，掠入射角分别为1.0、1.4和1.7度。将修改后的目标引入optilayer软件。Optilayer软件与IMD软件结合使用可获得良好的效果。讨论了分块法与针头优化设计结果的差异。
