1. A method, comprising:
receiving, by a microscope, a ferrule of a fiber optic connector via an opening of a connector adapter of the microscope, wherein a body of the fiber optic connector remains outside of the connector adapter when the microscope receives the ferrule of the fiber optic connector within a body of the microscope;
aligning, by the microscope, the ferrule of the fiber optic connector with the opening of the connector adapter of the microscope,
wherein the ferrule includes a ferrule endface;
transmitting, by the microscope, light onto the ferrule endface;
receiving, by the microscope, reflected light, as an image of the ferrule endface, with a camera of the microscope;
determining, by the microscope, intensities of brightness of the image;
creating, by the microscope, a topographical map of the intensities of the brightness of the image;
determining, by the microscope, a radius and an apex of the ferrule endface based on the topographical map;
calculating, by the microscope, an apex offset of the ferrule endface based on the radius and the apex of the ferrule endface; and
performing, by the microscope, one or more actions based on the apex offset of the ferrule endface.
