ior = 1.5
dispersion = 1.1
dispersion_count = 768
gather_min = 128
gather_max = 512

127+ million photons (highly diluted far from lenses...)

I could not get rid of the interference fringes, probably due to spiral pattern
of the shooting. The solution could consist in making them sub-pixel, but this
means also lower resolution for a smooth result, or even more photons! Another
shooting method could avoid these fringes.

The actual diameter of the incoming beam (cylindrical light_source) is smaller
than the one rendered, and corresponds roughly to the center part of it. Due to
gathering?

Render time: about 8 hours on a dual Xeon 3Ghz. I had to mask the prism side
pointing to the camera, otherwise, rays get lost forever inside the prism.
