在卡尔斯鲁厄理工学院（KIT）的微结构技术研究所（IMT），开发了一种新型的折射X射线光学器件。由于其简单的制造方法和大孔径，所谓的滚压X射线棱镜透镜（RXPL）有可能在工业环境中与X射线管一起使用，作为现有光学器件的低成本替代品。该透镜本身由微结构箔制成，该微结构箔被切割成一定形状并围绕卷绕芯卷绕以形成用于X射线的折射元件。所得折射结构可用作照明光学器件。衍射实验与NIST 1976a样品进行，并显示了高达18倍的增强的积分强度相比，与钢管准直器获得。
At the Institute of Microstructure Technology (IMT) of the Karlsruhe Institute of Technology (KIT), a new type of refractive X-ray optics has been developed. Owing to its comparably easy fabrication method and the large aperture, the so-called Rolled X-ray Prism Lenses (RXPL) have the potential to be used with X-ray tubes in an industrial environment as a low-cost alternative to existing optics. The lens itself is built out of a micro-structured foil which is cut into shape and rolled around a winding core to form a refracting element for X-rays. The resulting refractive structure can be used as illumination optics. Diffractometry experiments with an NIST 1976a sample were performed and showed up to an 18-fold enhanced integrated intensity compared to that acquired with a steel tube collimator.
