An improved setting device for providing accurately reproducible, incrementally variable control voltages to the input of a control and regulating circuit for adjusting electromagnetic coil current in magnifying lenses of electron microscopes. The setting device includes a digital counter, preferably a ...
Magnification is a very simple concept, but it sometimes can create confusion because of its own definition. The aim of this blog is to clarify magnification in scanning electron microscopes (SEM) and focus on other parameters which can describe better how big an object ...
