Optics Group (X-ray Science Division)

The mission of the Optics Group is to facilitate the efficient and productive use and operation of APS beamline-based research facilities.

In support of this mission, the Optics group:

  • Operates and develops instruments to fabricate and characterize x-ray optical elements, such as single crystal-monochromators, mirrors, multilayers, and other specialized optics and substrates.
  • Carries out R&D jointly with the APS beamline scientists and user community, independently or in collaboration with other facilities to keep the group at the state-of-the art in x-ray optics.

The group is composed of three sections: the first section focuses on mirrors, multilayers optics and metrology; the second section deals with crystal optics fabrications and topography; and the third section deals with the development of the optics and detector testing beamline.

Mirrors and Multilayer Optics

To help develop mirrors and multilayer-based optics as well as thin film coatings for experimental samples.




The metrology laboratory at the APS can evaluate optical quality of x-ray mirrors and substrates to be used in the APS beamlines, in order to ensure compliance with the user's specifications in terms of figure error and finish. The lab can characterize x-ray mirror-bender assemblies and specilized optics as well as carry out joint R&D programs to develop new metrology measurement techniques and instrumentation.
