The development of the first real microscope, an optical instrument that enlarges the image of any object, in Holland around 400 years ago has enabled scientists to study objects that would not have been visible to the naked eyes.. This has greatly aided in the discovery and study of what were previously called ‘mysterious’ components of living things that led to advances in science. Through the years, there were a lot of improvements in the field of microscopy. The development actually started from the lens makers who used their lenses to magnify certain objects illuminated by a light source in the microscope. Now, aside from the light microscope, there are other types of microscopes like the scanning electron microscope ( SEM ) and the transmission electron microscope, However, this article covers only the light microscope.
