Interferometry, surface profiling, and optical metrology itself were redefined by 4D Technology over two decades ago, when we expanded applications and environments which benefited from the speed and resolution of laser interferometers and optical profilers. 4D is the technology leader in interferometer manufacturing.
Dynamic Interferometry, the technology behind many of our optical metrology products, ensures excellent performance without vibration isolation or air turbulence control. Our technology leadership provides not just the capability to measure in extreme environments such as vacuum chambers, but makes precise measurements in prosaic environments like office spaces or shop floors easy and convenient.
Purchasing 4D laser interferometers means you get installation, training, the latest computer hardware, and industry-leading data analysis and visualization software. All 4D metrology systems are backed with a comprehensive warranty and a professional service team.
