QED Opens New Facility

Facebook X LinkedIn Email
QED Technologies International Inc. of Rochester, N.Y., has opened a renovated manufacturing facility for its new division, QED Optics. The plant is equipped with magnetorheological finishing (MRF), polishing and subaperture stitching interferometry (SSI) metrology systems and with a metrology tower for measuring large-aperture optics. QED Optics specializes in polishing and metrology of flats, spheres, on- and off-axis aspheres, free-form optics and cylinders and can work with optical components ranging from ~1 mm to 1 m in diameter. It employs proprietary MRF and SSI technologies and will help customers manage the full optics fabrication process.

Glossary
magnetorheological finishing
Magnetorheological finishing (MRF) is a precision optics polishing technique used for shaping and finishing optical surfaces to achieve extremely high levels of smoothness and accuracy. It is commonly applied to lenses, mirrors, prisms, and other optical components in various industries, including astronomy, microscopy, and laser systems. The process involves using a magnetorheological fluid—a liquid containing ferrous (iron) particles—and a magnetic field to perform the...
metrology
Metrology is the science and practice of measurement. It encompasses the theoretical and practical aspects of measurement, including the development of measurement standards, techniques, and instruments, as well as the application of measurement principles in various fields. The primary objectives of metrology are to ensure accuracy, reliability, and consistency in measurements and to establish traceability to recognized standards. Metrology plays a crucial role in science, industry,...
