altPrior Scientific (Rockland, MA) has added patent-pending Intelligent Scanning Technology (IST) to its Prior ProScan™ II H101A, H107, and H117, 4 × 3" scanning stages. IST allows each stage to be pre-programmed with a unique set of operating characteristics to that particular stage. The technology also allows the controller to periodically interrogate the stage and make adjustments to maintain orthogonality and metric accuracy.
