More Info on 4D Technology Corporation

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 is a subsidiary of Onto Innovation.  For more information visit www.4dtechnology.com.
