flatbed uv scanner

It's fairly well known that some items fluoresces when exposed to UV
light. Unfortunately, taking pictures of these items isn't so easy.
As I understand it, filters that filter out all light save for UV
light can be bought for select cameras, but the items I'm interested
in making pictures of (some currency and some sports cards) are better
suited to scanning. Unfortunately, I'm not really sure how to go
about doing this.

Any ideas?

You used to be able to buy UV tubes in a number of different sizes
compatible with standard fluorescent fittings (they are basically
standard tubes without the phosphor coatings on the inside).

I bought a couple for the making printed circuit boards in the 80s.
Larger, restricted UV wavelength, tubes are available for tanning beds.
Smaller types are used on hand held wands for detecting forged
banknotes.

Have a look around, and you might find one that fits the scanner you are
planning to use. I had an old Logitech hand scanner that used the same
size tube as the banknote scanners.

Any ideas as to what I should search for?

When buying a generic power adapter, you need to pay attention to such
things as the DC input voltage, amperage, and the outer / inner
diameters. I imagine I'd need to make similar considerations here,
but I'm not sure how I'd determine what those considerations are or
where to buy potentially non-standard fluorescent bulbs?

Length and width are the main things for compatibility, and check it has
standard fittings.
