4D Technology Corporation

4D Technology designs and manufactures laser interferometers, surface roughness profilers, snapshot micropolarizer cameras and handheld surface gauges, for accurate measurement of optics, optical systems and precision machined surfaces. Our measurement products utilize state-of-the-art technology that can be deployed in production environments, even in the presence of severe vibration and turbulence.

4D interferometers and optical profilometers are used daily in critical applications in astronomy, aerospace, optical testing and many other industries. 4D's history of innovation has changed how and where interferometric measurement can be used, from unique space-based projects to high throughput production of precision components.

4D has redefined the applications and environments that can benefit from the speed and resolution of laser interferometers and optical profilers. Dynamic Interferometry®, the technology behind many of our optical metrology products, ensures excellent performance in difficult environments, without vibration isolation or extensive air turbulence control.

4D laser interferometry products are sold as turnkey measurement systems, including installation, training, the latest computer hardware, and industry-leading 4Sight data analysis and visualization software. All 4D optical measurement systems are backed with a comprehensive warranty and a professional service team.
