Raster Scanning Spiral Pattern

Raster Scanning Techniques for Photonics Applications

The nPoint LC.400 series of controllers have several internal functions for use with raster scanning.  A traditional raster scan can be generated via the simple Raster Scanning GUI used in the traditional raster scan below. Additional raster scanning patterns can be generated via the arbitrary scan capability of the controller. This provides complete flexibility for […]

Piezo Stage Orthogonality

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 […]

What is Phase Lag and How to Measure It

Understanding phase lag is important when scanning at high speeds with piezo flexure stages. This article describes the phase relationship between the command signal and the stage response. The response is monitored using the internal (in this case capacitive) sensor. The bandwidth of a system is the key element to phase lag. Using control parameters […]

Position noise

The amplitude of the stage shaking when it is on a static command. It is usually measured and specified with RMS (1 σ) value. It is commonly used to define the resolution of the nanopositioners and is a combination of sensor noise, driver electronics noise and command noise, etc.
