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 optical metrology 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.
The world around us is in constant motion. 4D’s innovative measurement systems are designed for real-world, dynamic environments. We are transforming how and where laser interferometers are used. Innovative, dynamic and adapting: 4D Technology.
