Optical microscopes are useful instruments that are integrated into basic science, research, chemical industry, food manufacturing, medicine, etc. These microscopes are basically used to see very small objects, like microbes, fungi, bacteria, etc., because they're not visible to the naked eye. The basic principle of optical microscopes is the use of lenses and a great increase in the magnification of objects.
Although there are different types of microscopes, optical microscopes are considered the most common and versatile; many companies have them for sale at a wide variety of prices. The following describes the most commonly used optical microscopes, such as the composite microscope, the polarized light microscope, the fluorescence microscope, the electron microscope and the atomic forces microscope. Knowing these types of microscopes can be very helpful when deciding on their use.
