Request InfoMulti-layer Thickness and Surface MeasurementLumetricsWEST HENRIETTA, N.Y., April 5 -- With few moving parts and all-fiber construction, the Lumetrics DI 330 multilayer thickness and surface measurement solution provides a new alternative for noncontact, online measurement of optics, optical assemblies and coated optics products. The dual interferometer (DI) engine uses a 1310-nm LED to create reflections off single and multilayer surfaces and combines a 1550-nm internal laser to perform rapid and accurate measurements of these reflections and convert them to thicknesses and surface profiles. The design includes a closed fiber loop, with piezo...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra January 2024 IssueCompact PhotorelayThe TLP3476S photorelay in the S-VSON4T package from Toshiba Electronic Devices & Storage Corp. offers a high-speed turn-on time, helping to shorten test time for semiconductor testers.
