If you‘re interested in a complete product solution with grayscale camera and
16 filter wheels incl. illumination and UV excitation, take a look at

This is where Vladimir Gajic is working at who has recently provided a GUI
for/with Argyll (hope it‘s fine that I make a bit of advertisement for you,
Vladimir!)

6-7 Filters can give you moderate to good success depending on the range of
wavelengths you are interested in. Using a three channel camera you can sort
of imagine that you are actually using 3 x 6 filters, but there is still the
issue of debayering algorithm choices.
There is some recent work on using LED illumination and no filters to provide
the input. I think this method is very exciting. If anyone is interested in
the LED method I have some thoughts on already available luminaires.
As has been said, lots of possibilities.

Institute in Rochester, with Roy Berns and Mark Fairchild, where we were
explained the 'basics' of multispectral imaging and shown some examples of
the setup and results from some renown galleries art reproduction projects.
Roy Berns has done a great deal of work in the area, and his papers
on it are well worth reading.
Also, I guess this ties in with Graham's reply, I don't suppose it's
possible to do multispectral imaging using a Nikon or Canon RGB camera,
since we don't have access to the spectral channels information? And that
would only give us three channels to work with?
People have tried lots of techniques, including using a sequence of
special filters with conventional cameras.
