The optical quality of lenses increased and the microscopes are similar to the ones we use today. Throughout their development, the magnification of light microscopescloselight microscopeDevice that uses visible light and a series of lenses to produce an enlarged image of an object. has increased, but very high magnifications are not possible. The maximum magnification of a light microscope is around x2000. However, most of the microscopes that are used in schools can only reach x400 magnification.
