Now, this was taken with the Nikon ELWD 60x. I have this saved as being taken with the 1mm Corning fused silica, though i'll want to search my lab book and re-check that to make sure it makes sense to have taken this data. I took this plot on Dec 5th, 2008.
//the units don't mean much. i scaled everything so that it fit together. //
just the normal CTF: CTF(fspatial)=contrast(fspatial)/contrast(1/3um)
the integrated light intensity of the whole image
the contrast at 600um divided by the light intensity: Norm Contrast = contrast(1/600um)/light intensity
