In June 2013, it was announced that ZEISS, the international leader in the fields of optics and optoelectronics would acquire US-based Xradia, Inc - a medium-size company providing innovative 3D X-ray microscopes for industrial and academic research applications. The closing of the transaction was subject to the fulfillment of customary closing conditions including a required filing with the U.S. competition authorities with, when completed, Xradia, Inc. operating under the new name Carl Zeiss X-ray Microscopy, Inc. Xradia had been organzed around development of superior X-ray imaging solutions utilizing advanced X-ray computed tomography (CT) imaging methodology and optics to nondestructively produce 3D images of objects with exceptional spatial resolution and contrast. The firm's MicroCT and nanoCT product families combine with other imaging modalities to provide a multi length scale imaging solution spanning from centimeters, to angstroms in resolution. Used by the scientific research community and industry, the firm built on their earlier success in advanced semiconductor packaging development and failure analysis applications. Implemented successfully in biomedical and life science research, rock physics modeling for oil and gas exploration, nano-imaging applications, and advanced material development and characterization, Xradia's technology was based on proprietary X-ray optics and detectors. Xradia produces state-of-the-art far-field ambient environment imaging systems capable of 3D imaging with resolution below 50 nm. Xradia's commercial products have 3D resolution from the nanometer level up to several hundred microns.
