Nanopositioning Metrology, Gödel, and Bootstraps

Why External Metrology Matters in Nanopositioning More than 80 years ago, a discovery by Austrian Kurt Gödel put an end to the dream mathematicians had pursued for centuries: a final unifying “Theory of Everything” or the idea that a system could be devised strong enough to verify itself. Gödel’s findings may seem rather obvious, but […]

Nanopositioning: How Mounting and Environmental Conditions Affect Performance

Nanopositioning equipment manufacturers can follow the latest design rules and put the best components into their mechanisms and controllers, often to no avail. If the user does not take the time to follow best practices for mounting, figuring out a suitable supporting structure, the right cable draping, and environmental conditions, much of the intrinsic performance […]

Tracking Down Nanometer Instabilities: Every Detail Matters

When you work with nanometer resolution motion equipment, details matter. Instabilities can be caused by a variety of things, ranging from floor disturbances leaking past isolation systems, to acoustic energy coupled into the application structure, to tuning issues with the motion system embedded in the application, to resonant excitation of structural elements of the setup. In real life applications, instabilities […]
