4D Technology

4D Technology is a leader in innovative metrology products for measuring surface quality and surface defects on precision surfaces, as well as the surface and wavefront quality of optics. 4D's patented Dynamic Interferometry® technology enables 4D's laser interferometry products to measure in difficult environments, where vibration, air turbulence or rapid motion have traditionally prevented accurate measurement. Our attention to customer needs has led us to adapt our award-winning laser interferometer technology to a wide variety of applications, including factory-floor inspection, telescope mirrors and systems, biomedical research, environmental sensing and imaging and much more. We collaborate with institutions and companies to develop, and deliver, accurate metrology for tough environments and difficult measurements.
