4D Optical Metrology Products assure the quality of precision optics. Dynamic Interferometry assures the surface and wavefront quality, despite vibration or turbulence. 4D instruments, technology and software are everywhere optics are made.
Industrial Surface Measurement
4D Industrial Measurement Products put high-resolution 3D surface and defect inspection where it’s needed: right on the shop floor. Smart, fast, and easy-to-use gauges change the way you’ll think about inspection.
4D Technology is the leader in high-resolution surface and wavefront measurements for challenging locations and applications.
4D pioneered “dynamic” measurement technology, paving the way for entirely new classes of instruments that change how manufacturers and scientists think about measurement. From the world’s premiere astronomical observatories, to optical manufacturing shops, to aircraft flight lines, 4D gages and instruments provide 3D measures accurately, despite vibration and noise that stop other instruments in their tracks.
