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.

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.
