4D Technology
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.

Phasecam Twyman-Green Laser Interferometers
PhaseCam dynamic Twyman-Green laser interferometers provide high resolution measurements despite vibration and air turbulence. Dynamic Interferometry® enables PhaseCam laser interferometers to capture full wavefront measurements in as little as 30 microseconds—5000 times faster than conventional phase shifting interferometers. Compact and lightweight, PhaseCams make reconfiguring test setups simple and easy, without vibration isolation.
