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.
In other words, the fiber under 400x looks more zoomed-in (or more magnified) than 200x. The Field of View (FOV) directly defines the size of the object field which can be viewed through a microscope. For example, 400 m x 300 m is a typical FOV spec for fiber optic connector video inspectors. With this FOV parameter, it is straightforward to picture the image of a 125 m fiber on the screen. FOV is entirely determined by the design parameters within the microscope probe, including the overall Optical Magnification and the sensing area of the imaging sensor (CCD or CMOS).
