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 patented innovations have changed how and where interferometric measurement are used, from unique space-based projects to high throughput inspection of precision machined 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.
PhaseCam MWIR
4D PhaseCam systems are ideally suited for measuring infrared optics over long paths, for remote mounting in measurement towers or pressure vessels, and for other challenging test set ups. The PhaseCam MWIR accurately measures concave, convex and focal-components at mid-IR wavelengths. Tracking high thermal signature targets requires extreme precision. This optical system enables measurement of both uncoated and high reflectors. Which allows for multiple test set ups, while maintaining high accuracy wavefront measurements in both well controlled and turbulent environments.
AccuFiz D
The AccuFiz D is a short-coherence Dynamic Fizeau Interferometer that provides high accuracy measurements of flat and curved transparent optics. The device allows you to isolate and measure the individual surfaces of transparent optics. Measuring these thin transparent optics can be extremely challenging due to reflections from the two close surfaces. Creating a complex fringe pattern that is difficult to measure. AccuFiz D can measure plane parallel surfaces without the need for coating to erase unwanted fringes. AccuFiz D features a completely on-axis design, resulting in highly accurate measurements even on curved surfaces.
