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 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:

• 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.
