How Piezo Stages React to Temperature Variation

Jun 8, 2018 / in nPoint Blog, Uncategorized / by

Qualitative analysis Flexure-based piezo stages are essentially blocks of metal with flexure patterns that create a moving platform suspended from static frame via flexures. The sketch below shows a simplified flexure stage that moves in one direction when the piezo expands or contracts. A capacitive sensor is used as the feedback sensor and a preload […]

Piezo Stage Load vs. Settling Time

Mar 29, 2018 / in nPoint Blog, Uncategorized / by

To maximize the capabilities of piezo stages, it is important to understand how different factors contribute to the performance of the system. For many applications, the resonant frequency and settling time of a stage are of primary interest. In this blogpost we explore how the resonant frequency and settling time are affected by the load […]

Fundamentals of piezo stage design: range of motion, footprint and stiffness

Mar 14, 2017 / in nPoint Blog, Uncategorized / by

Piezo stages are used in applications where high precision in motion, very fast movements (in milliseconds), or high force generation out of a small volume (kilo Newton) are necessary. High precision in motion is required in Atomic Force Microscopy, for example. TappingMode™ image of indentation patterns on Parafilm® acquired with a MultiMode® AFM and an […]

How to care for your nPoint products

Oct 20, 2016 / in Uncategorized / by

A benefit of choosing an nPoint flexure-based nanopositioning system is that it requires minimal maintenance throughout its lifetime. Flexure-based designs are zero friction with no mechanical wear, thus routine maintenance is virtually eliminated. However, users should still consider a few important points to ensure that their stages and controllers perform optimally. The lifetime of nPoint stages […]
