Knowing the optical basics can be a great help for working at the microscope. This article describes the main components of optical microscopes, such as lenses, objectives and eyepieces, and explains elementary functions such as refraction, diffraction and reflection. You will read about the basic functioning principles of magnifiers and the “simple microscopes” derived from them, and finally also the principles of the “compound microscopes”.
