在极端离面安装中，以掠入射方式放置的高凹槽密度反射光栅可提供比 X 射线中传统面内安装更高的性能。我们展示了科罗拉多大学光栅评估设施针对离面配置进行优化的光栅的测试结果。测试的光栅是通过全息光刻技术生产的。测试的光栅具有径向凹槽图案，包括闪耀和正弦凹槽轮廓。我们展示了效率和子孔径分辨率结果。
High groove density reflection gratings placed at grazing incidence in the extreme off-plane mount offer improved performance over conventional in-plane mounts in the x-ray. We present test results from the grating evaluation facility at the University of Colorado for gratings optimized for use in the off-plane configuration. The gratings tested are produce via holographic lithography. Gratings tested have radial groove patterns and include both blazed and sinusoidal groove profiles. We present efficiency and sub-aperture resolution results.
