Full-field X-ray imaging and microscopy with polymer compound refractive nano-lenses is demonstrated. Experiments were carried out at beamline ID13 at the European Synchrotron and yielded a resolution of 100 nm. The lenses were demonstrated to be functioning even after an absorbed dose of ∼10 Gy. This article also discusses issues related to lens aberrations, astigmatism and radiation stability, and thus ways of improving the lens further are considered. Polymer nano-lenses are versatile and are promissing for nano-focusing and compact X-ray microscopy.
展示了使用聚合物复合折射纳米透镜的全场X射线成像和显微镜技术。实验在欧洲同步加速器的ID13光束线上进行，分辨率达到了100纳米。这些透镜在吸收剂量约为10戈瑞后仍被证明能正常工作。本文还讨论了与透镜像差、像散和辐射稳定性相关的问题，因此考虑了进一步改进透镜的方法。聚合物纳米透镜用途广泛，在纳米聚焦和紧凑型X射线显微镜方面很有前景。
