High Resolution Data Acquisition for Piezo Stages
In order to maximize scanning speed for photonics applications, it is often important to acquire recordings of nanopositoning stage sensor data synchronized with data collected from external sensors or detectors. The LC.400 series of controllers can record up to 8 streams of internal data simultaneously, including voltage signals measured via the...

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....

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...
Tip Tilt Piezo Stage Mirror Mounting
A tip tilt piezo stage provides the opportunity to dynamically scan a mirror with extreme precision and control. Piezo mirrors are used for laser beam steering and image stabilization applications. There are a variety of options built into nPoint systems for mounting purposes. Below are only a few suggestions, as...
