Request InfoTwice the Spatial Sampling 4D Technology CorporationTUCSON, Ariz., March 15 -- 4D Technology's PhaseCam 4010 is a high-performance, dynamic Tywman Green interferometer system that offers twice the spatial sampling of its original PhaseCam. Unlike old-style phase-shifting interferometers, the PhaseCam works by acquiring all of the information to compute a phase in a single exposure, and it is insensitive to vibrations. The PhaseCam 4010 includes an innovative single camera and a high-speed optical phase sensor that eliminates the need for slow, bulky phase shifters and can acquire data in as little as 1 sec. -- over 10,000 times faster than...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 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.
