4DTechnology
ABOUT4D Technology designs and manufactures laser interferometers, surface roughness profilers, polarization cameras and surface gauges, for accurate measurement of optics, optical systems and precision machined surfaces. Our patented Dynamic Interferometry technology enables optical metrology in difficult environments, where vibration, air turbulence or rapid motion previously have prevented accurate measurement. At 4D we are transforming how and where laser interferometers are used.
