Microscopy Essay

Microscopy allows one to view samples and objects that cannot be seen with the human eye. With all the modern techniques used in the biology field today, microscopy is one of the most important one that allows us to see a world beyond what our eyes limits us too. The majority of both organisms that are helpful and harmful are too small to be seen with the human eye, and without the microscope we would have not understood the mechanism behind the major diseases we know today. Microscopy has helped scientists produce antibiotics and antiviral drugs to treat the diseases that once were in a world beyond our vision. There are three types of microscopy mainly used: optical (light), electron, and scanning probe microscopy.

Optical microscopy includes Fluorescence, Bright field, and phase contrast. Optical or light microscopy allows magnification of an object by the passing of visible light transmitted from the sample through a single or multiple lenses to allow a magnified view of the sample.

Of all the optical microscopy, the Bright field microscopy is the simplest one due to the si...
