4D Technology Corporation was founded in January of 2002 by Dr. James C. Wyant and Dr. John B. Hayes (founders of Wyko Corporation), and Dr. James Millerd and Mr. Neal Brock (founders of 4D Vision Technology), for the purpose of developing and manufacturing metrology products for applications in aerospace, astronomy and optical fabrication, as well as for semiconductors and data storage. The founders transformed optical testing by simplifying measurements and enabling laser interferometer measurements in environments that were previously impossible. 4D was acquired as a business unit of Nanometrics in 2018.
4D built a world class staff experienced in laser interferometry, optical instrumentation, manufacturing, software development, quality systems, and customer support. The world's leading aerospace, astronomy and optics manufacturers now trust their most challenging measurements to 4D Technology, including: Ball Aerospace, Boeing, ITT Industries, NASA, Raytheon, Northrop Grumman, Sandia National
Laboratory, University of Arizona Mirror Lab, Nikon, Tinsley, Lockheed Martin, Lawrence Livermore National Laboratory, Steward Observatory, Corning, Alcatel, NIST, Agilent, Oceanit, and many more.
