Specializing in Piezo Stages and Nanopositioning Solutions

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 […]

Components of a Nanopositioning System

Nanopositioning systems provide the opportunity to enable many advanced applications. Their use has spread from AFMs to optics and multiple new technologies. While selecting a system can be complex at times, there are three main components that work together to provide motion on the nanoscale. Each component will briefly be discussed and can be studied […]

Piezoelectric Actuators Used in Flexure Stages

nPoint uses piezoelectric stack actuators to provide motion to its flexure stages. These stacks are often referred to as “piezos” and this is what puts the “piezo” in “piezo stage.” Actuators are stacked with multiple piezo tiles to provide larger displacement and hence the term “piezo stack”.  The material used for the piezo tiles is […]

OEM and Custom Piezo Stage Development

The goal at nPoint is to meet the specifications set forth by each customer. In many cases, this can be done with nanopositioning systems that have previously been designed and manufactured. There are however, many applications where a custom stage is necessary, such as a component of an OEM product. nPoint works with a variety […]

Parallel vs Serial Kinematic Flexure Stage Design

When designing piezo flexure stages two examples that dominate mechanical design include parallel and serial kinematics. At nPoint we employ both strategies to meet customer requirements. Testing and calibration are always done with external interferometric sensors regardless of flexure design and feedback sensor choice. Specifications tested in this manner are actual, not theoretical sensor or […]
