WebOct 2, 2024 · How do you find the diameter of a field of view? Field of View = Field Number (FN) ÷ Objective Magnification For instance, if your eyepiece reads 10X/22, and the magnification of your objective lens is 40. First, multiply 10 and 40 to get 400. Then divide 22 by 400 to get a FOV diameter of 0.055 millimeters.
