Note that the Raman scanner you found works only with [homogeneous] raw materials, and ultimately would only be able to tell you the composition at the very surface of the material, at the point scanned.
Going back to the video for the Tellspec, they scan a chocolate truffle, and post it's composition.... how could the scanner possibly know the composition of the filling?
I believe these people have an idea, but I think they have failed to see the shortcomings of the technology, and will ultimately fail to deliver [or under-deliver] on the promises they are making. If they do indeed make a Raman scanner, at that price, it certainly is an interesting device, that may find other applications, just not the one they are marketing with.
