When interpreting APC geometry results in order to modify the polishing process to improve results, it is important to understand Apex Offset—-namely, that Apex Offset (for both PC and APC ferrules) is really the result of two components: Angle and Key Error.
In the case of PC ferrules, Apex Offset and Angle (or Angular Offset) are essentially two ways of saying the same thing. The “Apex Offset” value measured by the interferometer is simply the distance (in microns) between the Apex point (the highest point of the radius) and the geometrical center of the ferrule (usually the exact center of the fiber). Ideally, we’d want both the Apex and the center of the ferrule to be in the exact same location—-an Apex Offset value of 0.
