Photo: Most microscopes have several different objective lenses that turn around on a thumb-wheel to give different levels of magnification. Going from right to left, the lenses you can see here magnify by twenty times (20x), forty times (40x), and a hundred times (100x). Photo by ...
The lenses are replaced by a series of coil-shaped electromagnets through which the electron beam travels. In an ordinary microscope, the glass lenses bend (or refract) the light beams passing through them to produce magnification. In an electron microscope, the coils bend the electron beams the...
