IMPORTANT: The Optical Science and Technology Center and Microfabrication Facility are being retired after fall 2018 and their services reconfigured under the new Iowa Center for Research, Exploration, and Advanced Technology in Engineering and Sciences (Iowa-CREATES) and Materials Analysis, Testing, and Fabrication (MATFab) in the Iowa Advanced Technology Laboratories (IATL) in spring 2019. As a result, the OSTC/UIMF site will eventually be taken down. Until then, please visit the Iowa-CREATES Website at, or read more about the new center at
