Request Info4D Technology CorporationTUCSON, Ariz., June 16, 2008 -- 4D Technology Corp.'s new series of PhaseCam laser interferometers are designed for accurate surface and wavefront measurements at wavelengths of 1.053, 1.064, 1.3 and 1.55 µm. PhaseCam laser interferometers employ a "dynamic" interferometry technology to acquire measurement data in less than 30 microseconds, 4D Technology said. Because acquisition time is so short, the instruments are insensitive to vibration and air turbulence, enabling use in difficult environments such as production floors, cleanrooms and environmental testing chambers. Beam ratio adjustment ensures maximum fringe...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 6/7/2022MWIR InterferometerThe PhaseCam MWIR interferometer from 4D Technology Corp. is a dual-port device that measures optical surface shape and wavefront error at a 3.39-µm IR wavelength for fast acquisition with...Photonics.com 6/8/2022On-axis Dynamic InterferometerThe AccuFiz® D on-axis dynamic interferometer from 4D Technology Corp. features a 600-mm aperture beam expander, measuring remote cavities, optical thickness, and homogeneity, even in challenging...Photonics Spectra September 2022 IssueFizeau InterferometerThe AccuFiz® Fizeau interferometer from 4D Technology Corp. now features a 9-MP camera for higher slope tolerance through superior spatial resolution.
