Request Info4D Technology CorporationPhaseCam® laser interferometers are compact and lightweight for highly accurate measurement of precision optics and optical systems. PhaseCam systems utilize Dynamic Interferometry® to acquire measurement information in less than 30 microseconds—more than 5,000 times faster than conventional, phase-shifting interferometers. Because acquisition time is so short, PhaseCams can be used without vibration isolation, making them ideally suited for in- situ measurement on production equipment or in noisy environments such as cleanrooms. Their insensitivity to air turbulence makes...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.
