Ultrafast Electron Diffraction Systems Made Accessible

Harness the Power of Ultrafast Structural Dynamics

We build compact Ultrafast Electron Diffraction (UED) systems that combine femtosecond temporal resolution with spatial precision that rivals — and often exceeds — modern ultrafast X-ray methods, without the cost or complexity of large-scale facilities.

About Us

Built by scientists, for scientists — our team has spent decades advancing UED at the frontier of research. Now, we’re making this transformative technology accessible to the ultrafast community, empowering more labs to explore ultrafast structural dynamics with accuracy and precision.

Products

From ultrafast electron sources to complete beamline systems, we offer flexible, high-performance solutions tailored to your research needs. Whether you’re building from the ground up or upgrading an existing setup, our technology is designed to accelerate discovery. Both our compact and RF-compression-ready systems enable temporal impulse response functions that approach 100 fs.
