Sigray is a 35 person company located in the San Francisco East Bay founded by Dr. Wenbing Yun with the mission of developing the next generation of X-ray analytical instruments based on its patented ultrahigh brightness x-ray source and high efficiency optics technologies. It has productized three major product lines that bring unprecedented synchrotron-like capabilities to laboratory systems in XRF microscopy, x-ray absorption spectroscopy, and 3D x-ray microscopy.

Sigray’s products have been installed globally and have been sold for a diverse range of applications, spanning from semiconductor metrology to 3D cellular imaging for biofuels.

The team is comprised of former synchrotron scientists and leaders, x-ray instrumentation and optics pioneers, the former CTO of a well-known x-ray source company, and Dr. Yun, who previously founded x-ray microscope company Xradia in 2000, prior to its successful acquisition by Carl Zeiss in 2013 as its x-ray microscope division.

The company holds 12 US and international patents and has received over $17M in government grants for the development of its breakthrough technology.
