Microscopes are used in a variety of fields to view objects or organisms that are not visible with the naked eye. These devices are useful in biology and medicine to study or analyze specimens, such as bacteria, cells and body tissues. Some other uses of microscopes include for crime scene investigations, mineral specimens and chemical materials.
At crime scenes, forensic scientists collect evidence, such as bullet cases, to examine under a comparison microscope. In geology, mineral and rock specimens can be studied under a microscope to study their composition. In chemistry, different materials, such as metals and atomic structure of elements.
There are different types of microscopes used in science, including compound, dissection, scanning electron and transmission electron microscopes. The images can be either two or three- dimensional depending on the microscopes. Likewise, the magnification varies with different microscopes. For example, the transmission electron microscope presents images in 2-D and has both a high magnification and resolution.
