What is Field of View?

The field of view is the distance of the observable area seen through a microscope or telescope. It represents how much of the sample or sky you can see at one time.

Example Calculation

Example 1:

Step 1: Divide the field number by the objective magnification:

\[ FOV = \frac{20}{10} = 2 \]

Example 2:

Step 1: Divide the field number by the objective magnification:

\[ FOV = \frac{25}{5} = 5 \]
