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. 4D Technology has been a Nanometrics business unit since November, 2018.
Using our unique and proprietary dynamic measurement techniques, our award-winning laser interferometer technology is used in to a wide variety of applications, including:
We collaborate with institutions and companies to create and manufacture accurate metrology for tough environments and difficult measurements.
