In a very lens which includes spherical aberration, the various rays from an axial item stage will on the whole intersect important link the lens axis at unique details immediately after rising in the graphic space. By tracing a number of rays getting into the lens at diverse heights (i.e., distances with the axis) and extrapolating from the graph connecting ray peak with picture placement, It might be attainable to infer in which a ray jogging quite near the axis (a paraxial ray) would intersect the axis, although this type of ray could not be traced straight by the ordinary trigonometrical formulation since the angles could be as well small for the sine desk being of any use.
