建立了一种基于配备Wolter镜的透射式显微镜的消色差软X射线成像系统。采用电铸复制工艺精密制造了聚光器和物镜的两面沃尔特镜。用26 nm~35 nm的宽带高次谐波脉冲通过聚光镜照射样品，由物镜形成无色差的透射式明场图像。在飞秒激光脉冲照射下，以约200 nm的空间分辨率记录了单发图像。显微镜实现无色差宽带成像的基本能力将导致具有阿秒量级极短照明脉冲的软X射线显微镜的发展。
An achromatic soft x-ray imaging system based on a transmission microscope equipped with a pair of Wolter mirrors was constructed. The two Wolter mirrors for the condenser and the objective were fabricated precisely by using an electroforming replication process. The samples were illuminated by broadband high harmonic pulses in the wavelength range of 26 nm to 35 nm via the condenser mirror, and transmission bright-field images without chromatic aberration were formed by the objective mirror. A single-shot image illuminated by a femtosecond laser pulse was recorded at a spatial resolution of about 200 nm. The fundamental capability of the microscope to realize broadband images without chromatic aberration will lead to the development of soft x-ray microscopes with extremely short illumination pulses on the order of attoseconds.
