Whereas the electron microscope uses a beam of electrons in place of light waves for visualization of objects. The light microscope, in which the magnification is obtained by a system of optical lenses uses light waves.Microscopes are continuously improved to enable us to have higher magnifications and better resolutions. Later improvements in the compound microscopes were made and Amici discovered an oil immersion lens, which enabled the scientists to study the characteristics more minutely. ![]() The characteristic morphological studies enabled by the discovery of powerful microscopes, helped scientists to classify microorganisms.These findings were confirmed after the development of a compound microscope by Robert Hooke. He described the size, shape, movement of bacteria, protozoa, and algae.Antony Von Leuwenhoek is considered to be the first person who has seen a microorganism through a simple microscope made by him with a magnification of 270-480 times.It may be defined as an optical instrument, consisting of a lens or a combination of lenses, for making enlarged or magnified images of minute objects. The magnitudes attainable by microscopes range from 100 X-10,000,000X. ![]() The magnification, it provides, enables us to see microorganisms and their structures otherwise invisible to the naked eye.
