Often, little effort is spent on setting up a camera for an inspection or measurement system. Even though people may know theoretical formulas, they rarely bother to use them. It is more common that people use a trial and error approach. This is often the case when people select a lens and imaging configuration for a camera. This paper examines the optical portion of a camera system. Some non-threatening and easy to use tools are described. These tools encapsulate imaging theory in a convenient format. Quick estimations of basic optical designs can be obtained by entering a few parameters. Features like field of view, resolution, and depth of field can be quickly obtained before mounting a lens onto a camera.
