Piezo stages are a unique class of actuators that can be a valuable tool, though they are often plagued with issues of high cost with limited travel, speeds, and bandwidth. In this video we will explore different types of Piezo actuator technologies and contrasts them to linear motor stages. Learn More
TDI scanning is a method to increase instrument throughput when imaging a biological sample or flow cell for DNA Sequencing. This video helps illustrate how Time Delay Integration constant velocity imaging works (also known as TDI). Learn More
Trigger on position technology allows external devices to read a signal at the particular position of the stage encoder counter while analyzing the object in constant velocity motion. This video covers the subdivisional accuracy error produced in optical encoders as well as a cyclical error that occurs in high resolution, high accuracy applications such as TDI Imaging.
