The electron microscope uses a beam of electrons and their wave-like characteristics to magnify an object's image, unlike the optical microscope that uses visible light to magnify images. As you can see, there are clear benefits and drawbacks to both types of microscopes. A light microscope, on the other hand, is cheap to buy and maintain. What part of the microscope reflects light? How are electron microscopes different from light microscopes and how is their ability to observe a specimen different quizlet? It is an instrument that uses light rays and lenses to enlarge images of microorganisms and other small entities. Only dead(fixed) organisms can be viewed. This means that objects that wouldnt have been visible on a light microscope are much clearer in an electron microscope. Each of these microscopes has distinct features and is suitable for different purposes from the magnification of simple objects such as living cells to complex objects such as the details of a nucleus in a cell. The resolution of a light microscope can be somewhat increased by better focusing the light, widening the opening of the light source and thereby increasing the amount of light coming through, and using different types of light with a shorter wavelength. http://www.mini-sem.com High magnification of up to 1,000,000x. -The space requirements are high.
