Lyncean Technologies, Inc. is located in Fremont, California and was founded in 2001 to develop the Compact Light Source (CLS), a miniature synchrotron x-ray source based on research performed at the SLAC National Accelerator Laboratory and Stanford University.

Unlike stadium-sized synchrotron radiation sources that require a highly technical support staff, the CLS fits in a typical laboratory space and is designed to be operated directly by academic or industrial end-users. By replacing the conventional "undulator" magnets found in the large synchrotrons by laser technology, the entire device scales down in size by a factor of 200. Unlike traditional laboratory sources, the CLS makes a narrow beam of nearly monochromatic X-rays which are adjustable in energy.

The first commercial Lyncean CLS was purchased in December 2012 by researchers from the newly formed Center for Advanced Laser Applications in Germany, a joint project of the Ludwig Maximilians University of Munich and the Technical University Munich (TUM). The Munich CLS was delivered at the end of 2014 and has been in routine operation since April 2015.
