Nikon and Hasselblad both make (expensive!) UV-passing quartz lenses,
as I recall, but this off-the-wall idea may be worth a try: tape a strong
close-up lens on a bellows (no other optics), and stop it well down
(maybe f22-32) with a removable (for focusing/composing) piece of black
paper with a hole cut in it (the right size for the f22-32 f-stop ---
FL = distance between the lens and film; FL/f32=diameter of hole wanted
[for rough figuring]).
Since the CU lens has relatively little glass in it, it should pass
a fair amount of UV. Using the normally VERY soft single-element lens
at f32 or so should produce passable sharpness (and DOF! ;-) for at
least some experiments. BTW, the above is for actually shooting with
UV light, but that may not be necessary if the UV light on the subject
causes a visible-light effect - it can be photographed by normal-light
gear/film, since you see the effect by normal means...
Hope This Helps
