El-nikkor lenses pass a lot of UV. It's been a while since I ran the
tests, but I believe they pass 60 % of light (or more) at 330nm. I'll
check it again next week if anyone is interested.
I have produced enlarged cyanotypes using a 5000 watt olec UV lamp
mounted atop my 8x10 Saltzman. I've never tried platinum or gum, though
it's on my list of things to do. Hope this helps - Ed
