Super-Resolution Optical Microscopy, Nanoscopy, and Nanopositioning Motion Control

Much has changed since the first optical microscope was designed in the late 16th century by Hans and Zaccharias Janssen, two Dutch spectacle makers. For the first time, their invention put multiple lenses to use, resulting in much higher magnifying power than a single lens could achieve. For almost 400 years optical microscopy did not […]

Sensor Influence on the Precision of Piezo Positioning Stages

The choice of feedback sensor is one of the key performance factors of a piezo positioning stage. Below is a comparison between the two most commonly used sensors. When the absolute positioning information plays a critical role in scientific results, researchers prefer capacitive sensors. When cost is most important and / or results are based […]
