KNOWLEDGE CENTER ::
WHITE PAPERS
The following section covers a variety of technical topics related to precision
positioning and motion control. It is our goal here to provide material that will
help prospective users reach an informed decision concerning the suitability of
specific positioning components for their applications. We have noted the general
dearth of information of this type, and are familiar with the tendency to hype "specs"
at the expense of substance. Glib claims of "sub-micron accuracies" in particular,
only have meaning when a comprehensive errror budget is prepared, taking an integrated
approach to both the positioning components and the specifics of the application.
We take our responsibility seriously as vendors of secondary reference standards
for dimension. We also feel that our customers are better served by having more
information at their disposal, not less. Feel free to contact us should you wish
to discuss any of the material presented here, or examine the specifics of your
application. We look forward to serving you.
