QED Technologies Announces New and Improved Metrology Tool for Aspheres

ROCHESTER, N.Y.--(BUSINESS WIRE)--June 17, 2008--QED Technologies (QED), the pioneer and unique provider of Magnetorheological Finishing (MRF(R)) and Subaperture Stitching Interferometry (SSI(R)), today announced the release of its new SSI-A(R), QED's latest metrology tool for aspheres.

This new product expands the capabilities of QED's metrology products that were first introduced in 2004, to include full aperture measurement of aspheres with more than 200 waves (120 microns) of departure from best fit sphere, without the use of null lenses. This contrasts to just a few waves of aspheric departure for standard interferometers. Combining all the advantages of the SSI(R), for bigger or steeper optics metrology, the new SSI-A(R) incorporates an enhanced stitching engine that provides improved measurement accuracy over a broad range of aspheres. The new metrology system is also capable of taking full aperture measurements of spheres and flat surfaces.

"This new release is the next step in QED's product development roadmap," said Marc Tricard, Director of Business Development for QED. "QED strives to simplify optics manufacturing even as complexity, volume and quality demands in optics system designs become more challenging. We want manufacturers and end users to have confidence that their final product will be right on specification, reliably and consistently. This new SSI-A(R) is a flexible, easy to use yet powerful tool that serves optics manufacturers for both in-line and final metrology inspection of aspheres, spheres and flat surfaces."
