Read the lens position again. The difference in these two positions is the longitudinal chromatic aberration of the lens. It will very nearly be the difference in the focal lengths of the lens for red and blue light since the arc source is much farther business plan startup snowboard company

"WebChromatic aberration, as the name implies (khroma=color in Greek) is the phenomenon of white light wavefront splitting into its spectral components' (i.e. individual wavelengths) wavefronts, as light encounters media of different optical density. It is caused by different wavelengths moving at different speeds through media denser than air. " - Spherical aberration vs chromatic aberration
