Description
This course is a complete and practical introduction to scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS). These are essential techniques used in materials science, nanotechnology, engineering, electronics, and many other fields.You will learn how a scanning electron microscope works, including the function of key components like the electron source, lenses, apertures, and detectors. We will go through how the image is formed, how to adjust beam intensity and accelerating voltage, and how different signals such as secondary electrons (SE), backscattered electrons (BSE), and characteristic X-rays are generated. You will also discover how to interpret SEM images, identify contrast sources, and avoid common problems such as charging or image drift. The EDS part of the course will guide you through the basics of X-ray generation, how to read EDS spectra, and how to recognize individual elements based on their characteristic peaks.The course is designed for students, lab technicians, engineers, and early-career researchers. No advanced physics or complex math is required. All concepts are explained step by step using practical examples, simple illustrations, and a clear structure.To help you apply your knowledge, the course includes access to a free SEM and EDS online simulator. This allows you to practice without needing access to a physical lab.If you want to truly understand what you are seeing under an electron microscope, this course is made for you.
