The Difference Between Calibration and Image Linearity

Extract

In my last article, I discussed the need for scheduled system checks on scanning electron microscopes. The article used an experience at a local SEM laboratory to point out the importance of monitoring your instrument by performing simple but regular system performance evaluations.

In this article I will discuss some principles behind the performance of imaging systems such as scanning electron and scanning probe microscopes. We will talk about the concepts of image linearity and dimensional calibration.
