QED Technologies Announces Introduction of its QIS(TM) Measurement System

Rochester, NY, May 21, 2012 (GLOBE NEWSWIRE) -- QED Technologies International Inc, (QED), pioneer and exclusive provider of Magnetorheological Finishing (MRF®) polishing and Subaperture Stitching Interferometry (SSI®) metrology platforms for the precision optics industry, announces the release of its QED Interferometer for Stitching (QISTM) system.  The QIS system, developed and manufactured by QED Technologies, provides greater capabilities to QED's metrology product line and is optimized for stitching.

"The development and production of QIS is a big step forward for QED and our customers," said Andrew Kulawiec, President of QED Technologies.  "Until now, our metrology systems have utilized a general purpose interferometer.  However, increasing customer requirements led us to design, engineer and manufacture an interferometer specifically for stitching.  As a result, we optimized the optical design, features and capabilities of the interferometer allowing us to further improve our stitching algorithms.  Our customers now should be able to measure a greater variety of parts with improved accuracy, speed and ease of use."

QED's QIS incorporates hardware and software features designed to enhance the performance of QED's metrology products.  The proprietary QIS coherent imaging system affords the user the ability to obtain measurements with higher fringe densities and greater contrast.  The advanced optical design of QIS is engineered to reduce common errors, such as retrace and magnification errors.  In addition, the greater focus travel provided by QIS allows for the measurement of parts with shorter radii than possible with a general purpose interferometer.  QIS was also designed using the same software platform, QED.NET, as QED's metrology and newest MRF systems, which enables seamless communications between systems.  These features result in ease of use, efficient processing, increased accuracies and expanded capabilities.  QIS is available on the new ASI(Q)TM platform, or as a field upgrade to existing ASI® and SSI-A® platforms.  QIS will be introduced at the Optatec tradeshow in Frankfurt Germany, May 22-25, 2012.
