Abstract:Extreme ultraviolet (EUV) normal-incidence optical systems are widely used in biological structure microscopic imaging, plasma diagnosis, solar physical observation, and EUV lithography. Therefore,these systems warrant further study. In this paper,the latest developments of the EUV nor• mal-incidence optical system at the Institute of Precision Optical Engineering(IPOE)of Tongji University are presented. Several normal-incidence optical systems used in different applications,such as

These systems have achieved excellent performance in their respective applications,achieving spatial resolutions of several microns at a millimeter scale field-of-view(FOV)and realizing ultrahigh spa•
