极紫外、X射线为微观物质认识、宏观空间探测提供了高精度的观测手段,但这类观测的实现需要大量高精度光学反射元件的支撑。由于极紫外、X射线在光学表面更易发生散射,其光学反射镜基底的精度需求和制作技术也明显区别于长波元件。近年来,同济大学精密光学工程技术研究所建立了极紫外、X射线反射元件基底的超精密加工与检测平台,研发了超光滑非球面的离子束修形技术,提出了基于泽尼克多项式的随机离轴旋转绝对检测方法,形成了极紫外、X射线光学用反射镜基底的高精度全流程研制技术,并将该技术成功地应用于国内和国际短波光学大科学装置中。本文综述了本课题组在极紫外、X射线用反射镜制作领域中的研究进展。
High-precision extreme ultraviolet and X-ray observations for space exploration require the development of advanced micro materials for the numerous high-precision optical reflection elements used in such observations. Because short wavelengths are more prone to scattering on optical surfaces, the precision requirements and the fabrication techniques of short-wavelength optical components differ significantly from those of long-wavelength optical components. The Institute of Precision Optical Engineering (IPOE) at Tongji University has 20 years of research experience in this field. We have built a high-accuracy fabrication and measurement platform based on short-wavelength mirrors, developed an ion beam configuration of an ultra-smooth aspheric surface, proposed an absolute measurement method using random off-axis rotation based on Zernike polynomials, and formed a complete technology chain to develop aspheric reflector substrates. These optical components and systems have been successfully applied at several short-wavelength science facilities both in China and abroad. This study will briefly introduce the recent research progress on these optical aspheric reflectors at the IPOE.
