Request InfoCombines Vibration Insensitivity with Short Coherent Source4D Technology CorporationTUCSON, Ariz., Aug. 31, 2006 -- 4D Technology Corp., a manufacturer of dynamic laser interferometers, announces the introduction of its latest Fizeau instrument, the FizCam 2000. "This is a first-of-its-kind 'on-axis' vibration-insensitive Fizeau featuring a short coherence length source that enables measurement of transparent samples and assemblies which are difficult or impossible to measure with traditional laser interferometers," said James Millerd, 4D chief technology officer. Typical long coherence interferometer systems produce multiple fringe interference when measuring parallel optical surfaces such as glass...See full productRelated content from Photonics MediaPRODUCTSPromoted Content October 2023 IssueNear-Eye Display Test SolutionThe diversity of XR devices and their measurement requirements continue to grow — new display types, fields of view, resolutions, focal distances, form factors, and unique combinations of these...Photonics Spectra September 2022 IssueMultispectral IR DetectorsThe Pega and Capyork multispectral linear array IR detectors from Lynred are designed for integration into imaging satellites, tracking and measurement instruments used in water cycle observation and...Photonics Spectra March 2023 IssueUV CameraThe ATX081S-UC 10GigE PoE+ UV camera from LUCID Vision Labs Inc. is equipped with the Sony 8.1-MP CMOS IMX487 global shutter sensor for capturing images across the 200- to 400-nm UV range.
