Hi Norman I took some IR photos with my Lightphase before I got it fitted with an IR filter. Now I have a ccd chip back which is like all the other ones (as far as I know) with an IR filter permanently attached just in-front of the chip. So as an answer to your question: I doubt you could use any of the digi cameras we are familiar with to shoot IR, there may be some sort of specialist scientific kit that could do the job, or, if you have a LARGE budget you could buy an old Lightphase back for �3-�4K which doesn't have an IR filter. As for UV, I'm not sure how sensitive to UV the chip would have to be to make a useful image.
