Nov 20, 2018 · To name one disadvantage of the light microscope, it does not possess some of the advanced capabilities of fluorescent or electron microscopy because it only uses white light. However, electron microscopes and fluorescent microscopes range in price from tens of thousands to hundreds of thousands of dollars, while a compound microscope currently can be purchased for as little as $100.
Light microscopy is a very useful tool in biology because the light used to image the sample does not tend to kill it. On the down side, we are limited in how much we can magnify a sample because the wavelength of light is quite long, as compared to the wavelength of the electron beam used in electron microscopy.

A light microscope consists of a two-lens system for magnifying small objects. The first lens is called the objective. It creates an image of the object in the intermediate image plane. This image in turn can be viewed with another lens, the eye-piece, to provide further magnification. Light microscopy is commonly used in bioplastic studies.
