XOPT2026 will be held on-site.
If your paper is accepted, we will ensure a platform for it to be presented.

Welcome address

We are pleased to host the 11th International Conference on X-ray Optics and Applications (XOPT2026) as part of the Optics and Photonics International Congress 2026 (OPIC2026).

X-rays have played a vital role in many breakthrough scientific discoveries in recent years. Continuous innovations in X-ray optics, methodologies, and beamline instruments have laid the foundation for these achievements. For this conference, we are inviting leading experts in these fields worldwide to share the latest status of X-ray technology and developments and discuss their plans for the future.

The three-day XOPT 2026 program will feature oral sessions that include contributed and invited talks, and a poster session. These sessions will cover a wide range of topics, including advancements in state-of-the-art X-ray sources such as 4th generation synchrotron radiation (SR) sources, advanced XFELs (X-ray Free-Electron Laser), novel X-ray optics and beamline instruments, and cutting-edge X-ray imaging techniques driven by AI and innovative algorithms.

We hope that XOPT2026 will provide a platform for meaningful discussions for all participants and contribute to further advancements in this field.

As a part of OPIC2026 on April 21-23, 2026, participants in XOPT2026 will have a full access to all the other concurrent conferences, events and exhibition (OPIE2026). See http://opicon.jp/ for details.
