About Top Unistar and XRnanotech
XRnanotechis a high-tech enterprise derived from more than a decade of frontier research and development at the Paul Scherrer Institut in Switzerland, officially established in 2020, dedicated to bringing breakthrough innovations in nanoscale optics to industrial application. Among them, Mciroworks GmbH in Germany is a subsidiary of XRnanotech, highly skilled in using LIGA technology to fabricate high-aspect-ratio micro- and nanostructures.
The company's vision is to empower optical instruments worldwide to fully realize their performance potential and break through existing technological boundaries; its mission focuses on developing and manufacturing nanoscale optical components of the highest level, achieving ultimate optimization in key metrics such as resolution, efficiency, stability, and structural design.
Its product line includes: extreme ultraviolet (EUV) and X-ray Fresnel zone plates, X-ray phase-contrast gratings, diamond optical components, X-ray micro/nano-resolution test targets, metalenses, and neutron gratings, with applications spanning frontier directions such as X-ray scientific research, materials analysis, and medical imaging. Leveraging its unique Ir-line multiplication technology,XRnanotech it can fabricate Fresnel zone plates with resolution as low as <10nm, and offers various materials such as gold, nickel, silicon (silicon dioxide), iridium, chromium, and even diamond.
TopUnistarAs the SwissXRnanotechcompany's exclusive agent in China, Top Unistar provides all pre-sales consultation, sales, and after-sales services to Chinese users. Meanwhile, as a leading service and solution provider in the EUV and X-ray field, Top Unistar has built up a certain scale ofinventory of EUV and X-ray related equipment and core components, enabling rapid delivery to better serve our users.
