My first post to this list and it has little to do with PICs
specifically :)

An ordinary magnifying glass will bend UV light quite well, problem is
that little to none of the UV light will make it through the lens. Of
course, the amount of UV that is transmitted is highly dependent on the
glass that is used in the lens. Also consider that a lot of the cheaper
magnifying glasses are made of plastic these days. Who knows, you might
get lucky and have a lens that will transmit enough of the 254nm light
to actually work better than no lens at all. I don't think a plastic
lens would last very long though.
