Air Bearings are Critical in CMM and Metrology Applications

Air bearings have played a crucial role in the development and construction of coordinate measuring machines (CMMs) and other metrology tools for decades. Since they are inherently frictionless and highly stable, air bearings play a key role in delivering the precision required in metrology equipment. Performance criteria, such as repeatability and minimized error motions, geometric […]

Surface Slope Metrology: High Precision Tilt Stage Achieves 30nrad Absolute Accuracy

A recent paper shows significant advances in the accuracy of long trace profilers, auto-collimator based deflectometers, and other surface metrology instrumentation. Scientists at the ALS X-Ray Optics Laboratory, HZB/BESSY-II and PTB devised a new universal calibration method for deflectometers.  One key component in the system is a high accuracy, piezo-motor-driven flexure tilt stage developed in […]

Automation and Microscopy: Faster Test & Measurement, Surface Metrology – Piezo Speed is Enabler for 100% Testing

Everybody who commutes by car is familiar with the concept: constant velocity gets you faster to your destination than stop-and-go traffic. This well-known principle from the macro-world is now employed in the nano-world by scientists from the Fraunhofer Institute for Production Technology IPT in Aachen, Germany. Their solution speeds up microscopic testing of large-surface objects, […]
