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.
Twyman-Green Interferometers
PhaseCam laser interferometers are the industry choice for measuring surface shape of large focal optics and aspheres, and for determining the quality of complex optical systems.

Fizeau Interferometers
Fizeau interferometers are the workhorse of optical manufacturing because of their versatility for measuring flat and curved optical components. AccuFiz Fizeau interferometers produce accurate, repeatable interferometric measurements of surface shape, radius of curvature and transmitted wavefront quality.

Optical Profilers
Optical profilers from 4D measure surface roughness and defects on smooth and supersmooth surfaces. 4D profilometer measurements are non-contact and immune to vibration. The NanoCam HD is extremely portable and perform in challenging environments. The 4D InSpec Surface Gauge is the first handheld, precision instrument for non-contact measurement of surface features and defects.
