We report on fullerene interference experiments using the two abundant fullerenes CView the MathML source and CView the MathML source. Compared to previous experiments the detected molecular flux has been improved by about an order of magnitude. This now permits either a better collimation or a velocity selection. In both cases, demonstrated here, we see a good improvement of the interference contrast for both fullerene species. In the case of CView the MathML source the interference minima go down to the background level — indicating almost perfect coherence.
