"WebThe first basic principle of through-focus MTF is the geometrical limitation. Any lens that focuses light produces an “illumination cone.”. See below for an example: The light from the lens comes to a focus and then expands again, as it should. The diameter of the illumination cone (called the spot size) is very small at the focus but it is ... " - Optics mtf
