Request InfoQED Technologies Inc.QED Technologies International Inc. has released its QED Interferometer for Stitching (QIS) system. Until now, the company’s metrology systems have used a general-purpose interferometer. Customer requirements have led to one with improved stitching algorithms. The QIS incorporates hardware and software features that enhance the performance of the company’s metrology products. The proprietary QIS coherent imaging system provides measurements with higher fringe densities and greater contrast. The optical design reduces retrace and magnification errors, and the greater...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra August 2023 IssueSemiconductor Metrology ToolThe FRT MicroProf® PT from FormFactor Inc. is a metrology and inspection system for high-throughput panel measurement in advanced packaging.
