Request InfoQED Technologies Inc.QED Technologies has unveiled its aspheric stitching interferometer, which measures steep aspheres with as much as 1000 waves (more than 600 μm) of departure from the best-fit sphere, without the use of dedicated null lenses or computer-generated holograms. The device is based on the company’s subaperture stitching technology.See full productRelated content from Photonics MediaPRODUCTSPromoted Content January 2024 IssuePrecision Optics + AssembliesSince 1947, three generations of family leadership have guided LaCroix Precision Optics to become the premier precision optics manufacturer in America.
