How Piezo Stages React to Temperature Variation

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

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 […]

Choosing a Controller Interface

There are several interfaces available for the LC.400 series, each providing a unique way to interact with the nPoint controllers.  First we will cover the interfaces that come with every standard LC.400 series controller, and then we will describe the optional interfaces that can be added. Standard Interfaces USB Port – All nPoint controllers are […]

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

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

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 […]
