The Dimensional Metrology Group in the Semiconductor & Dimensional Metrology Division of the Physical Measurement Laboratory (PML) at the National Institute of Standards and Technology (NIST) performs research to advance the state of the art of in all forms of coordinate dimensional metrology and develop methods to characterize the performance of both new and existing systems. It is critical that new technology be characterized to the degree that U.S. Industry will understand its capabilities, both strengths and weaknesses, and that accurate decisions to adopt new technology can be made. Our knowledge of advanced systems performance is used to actively support international and national dimensional metrology standards committees by our participation and leadership and with emphasis on rigorous uncertainty evaluation. We have a suite of coordinate measuring machines in environments that allow us to make the most accurate measurements available on critical parts, prototypes and fixtures. We also realize and disseminate the SI units of length, concentrate on dimensional measurements over seven orders of magnitude, from micrometers to several kilometers and provide the delivery of those measurements, standards and infrastructural technology services that promote U.S. innovation and industrial competitiveness.
