Could this be the product to finally disproves the whole "you can't beat physics" argument to lenses needing to be a particular size?

Even if this lens worked perfectly for all wavelengths, it would only save length, not diameter.  You can't get around needing aperture.  Saving length would be nice, of course, but it's not the only dimension that matters.
