我们制作并测试了一种复合透镜,该复合透镜由四个相形透镜阵列组成,用于测量11.3 keV的硬x射线光子。我们的数据表明,在保留透镜功能的同时,使用多个透镜可以超过临界角限制,这为纳米级及以下分辨率的硬x射线光子的实用聚焦光学提供了一条途径。
We have fabricated and tested a compound lens consisting of an array of four kinoform lenses for hard x-ray photons of 11.3 keV. Our data demonstrate that it is possible to exceed the critical angle limit by using multiple lenses, while retaining lens function, and this suggests a route to practical focusing optics for hard x-ray photons with nanometer scale resolution and below.
