Chapter 1.5, Problem 1CR
Summary Introduction
Microscope is a fundamental tool used to study the size and shape of the microorganisms. It magnifies the cell size and other smaller objects. In order to visualize microorganisms, the microscopes are the right choice to view their size and shape of the cells. A typical microscope consists of an eyepiece, objective lens, and light illuminator to visualize the cells or small objects with good magnification and resolution abilities.

- The field of view (FOV) is the entire circular image we see when looking into the eyepiece. The diameter of the FOV gets smaller as we increase magnification. It can be measured by using a stage micrometer like a ruler, measuring from edge to edge. Notice that the stage micrometer is 1000 microns (µm) in length, and the field of view under the lowest magnification is 5000 µm.

- Which of the following is true about the relationship between depth of field and magnification? There is no relationship. When magnification increases, depth of field decreases. When magnification increases, depth of field increases. Stereomicroscopes offer a lesser depth of field than compound microscopes.
