This magnification value determines the diameter of the field of view when the low power objective is used. A microscope's field of view refers to the diameter of the circular optical light that is visible when viewing an object under the microscope. This value forms an inverse relationship with magnification, which means that increasing the magnification results in the reduction of the field of view.
Microscope Calculations: Field of View, Object Size, Drawing Magnification When looking into a microscope, you will see a lit circular area. The distance across the center of the circle is referred to as the diameter of field of view (dFOV). To calculate the dFOV, you will need to place a transparent ruler on the microscope stage and measure the dFOV under low power. Looking at the diagram below, we can see that the dFOV for this particular microscope is 5 mm.
