Orthogonality Correction for Piezo Flexure Stages

nPoint is now offering an easy way for correcting the orthogonality error of XY scanners for the most demanding scanning applications. This capability is primarily used by OEM customers in applications such as Atomic Force Microscopy (AFM). An external method for measuring the orthogonality error is necessary prior to applying such correction. The AFM application […]

Piezo Stage Sensors for Closed-loop Control

A position sensor is necessary to provide closed-loop control for the nanopositioning system.  There are different types of sensors that can be used to provide the measuring feedback to eliminate inherent issues with piezos such as non-linearity and hysteresis.  Three common types of sensors include capacitive, strain gauge, and LVDT.  Each has advantages for certain […]
