Company Profile

QED Technologies, Inc. with operations also in Japan, Europe and Australia, is the pioneer and exclusive provider of Magneto-Rheological Finishing (MRF®) and Subaperture Stitching Interferometry (SSI®) technologies for the precision optics industry. MRF® combines magnetic fluids with sophisticated computer programs and computer controlled machines to create a patented process that deterministically improves both shape and surface accuracy simultaneously. Very SBIR-active in the period 2000-2006 - in July 2006, QED having became a wholly-owned subsidiary of Cabot Microelectronics Corp. (NASDAQ:CCMP). The relationship with CMC further strengthens QED and allows the company to achieve continued growth while maintaining its commitment to provide innovative products that set new standards in manufacturing precision optics. As of October 1, 2020 Cabot Microelectronics Company is known as CMC Materials. In July 2022, CMC Materials was acquired by Entegris (Nasdaq: ENTG). QED is now part of Entegris.SSI® improves the capacity and accuracy of a standard interferometer by measuring subsets of an optical surface and "stitching" those measurements together, creating a map of the entire surface automatically. MRF is proprietary surface figuring and finishing technology developed by QED which outperforms traditional finishing technologies and has the unique ability to predictively improve both figure and surface finish simultaneously. With more than 100 systems in operation worldwide, MRF is acknowledged as the best-in-class technology for final figuring of the highest precision optics. Subaperture Stitching Interferometry (SSI®). Interferometers, which measure the surface of an optic, traditionally are limited by the size and precision of the reference optic used. SSI is designed to remove those barriers, giving the user an accurate, complete map of the optical surface. This map is needed to produce the highest precision optics to the most exacting tolerances. Upcoming products are expected to extend SSI to include aspheres and freeform shapes. In combination with MRF, SSI enables the transition from time-consuming, costly, labor-intensive processes to repeatable, efficient automation in producing precision optical surfaces.
