Absolutely! Arcs and coronal discharge produce lots of UV. A coronal
discharge is pretty cold and does not produce much IR at all. You probably
won't even detect a coronal discharge in the IR. An arc must be pretty
'hot' to produce IR, but even a 'cool' arc will produce UV. Forget the IR
and go for the UV sensitive optics.
