QED Technologies International, Inc. Company Profile

Pioneers of Magnetic Fluid Polishing Technology (MRF) and Stitching Interference Measurement Technology (SSI. We provide innovative solutions to the precision industry.

QED is a development manufacturer based in Rochester, New York. With its core technologies of MRF, an advanced polishing technology, and SSI, a high-precision aspheric measurement technology, it meets various needs in the precision optics industry. MRF is a polishing technology that uses a magnetic fluid to generate a polishing tool a few millimeters in size, which scans the entire optical surface to correct its shape with high precision. Regardless of the size or tilt of the workpiece's shape, it finishes the optical surface to a perfect shape. SSI is an interferometric measurement technology that connects the results of interference measurements from multiple sub-apertures, enabling high-precision measurement of the entire inspected surface. It allows for the measurement of aspheres and freeform surfaces without the need for dedicated null optics. Since its establishment in 1996, over 300 MRF/SSI devices have been utilized by more than 100 users worldwide.
