All good stuff, but the critical thing about UV is its wavelength - anywhere from 10nm to 400nm.
Below 300nm, dangerous to people - above that is mainly UV-A which is not too bad - its like cholesterol - there is bad (LDL or all UV *except* UV-A) and "not so bad" (HDL or UV-A) :) I was discussing this on a valve (tube to everyone else) audio forum in the UK - I should point out its a very quirky forum full of strange people (like me), so the tone (of the discussions) is somewhat off-beat,,, random, even... However, the thread moved into interesting territory as some of our members are professionally into serious lens design for photo-lithography etc and some really interesting contributions were forthcoming. If such things amuse you, you could do worse than have a look at http://www.audio-talk.co.uk/phpBB2/viewtopic.php?t=4920 Nick -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
