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. 4D Technology has been aNanometricsbusiness 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:

Factory-floor inspection

Telescope mirrors and systems

Biomedical research

Environmental sensing and imaging

And much more

We collaborate with institutions and companies to create and manufacture accurate metrology for tough environments and difficult measurements.
