There are even some microscope designs that combine both the slides and the cells into one single unit. Electron microscopes differ from light microscopes in that they produce an image of a specimen by using a beam of electrons rather than a beam of light. Light passing through a specimen in a light microscope scatters due to the properties of the various substances in the specimen. They also require samples to be thinly sliced and mounted on a metal grid before they can be viewed, which can be time-consuming and may alter the sample in some way.
