There are many types of microscopes, and they may be grouped in different ways. One way is to describe the method an instrument uses to interact with a sample and produce images, either by sending a beam of light or electrons through a sample in its optical path , by detecting photon emissions from a sample, or by scanning across and a short distance from the surface of a sample using a probe. The most common microscope and the first to be invented is the optical microscope , which uses lenses to refract visible light that passed through a thinly sectioned sample to produce an observable image. Other major types of microscopes are the fluorescence microscope , electron microscope both the transmission electron microscope and the scanning electron microscope and various types of scanning probe microscopes. Although objects resembling lenses date back 4, years and there are Greek accounts of the optical properties of water-filled spheres 5th century BC followed by many centuries of writings on optics, the earliest known use of simple microscopes magnifying glasses dates back to the widespread use of lenses in eyeglasses in the 13th century.
