Subject: Re: [Homebrew_PCBs] UV lamps?

I'd recommend a single bulb fixture - the smallest you can get a lamp for - and back it up with a parabolic reflector. You will be trading light columination for intensity while trying to maintain uniformity over the exposure area. Good columnation and high intensity are good for resolution. Unfortunately if you stick the bulb smack against the artwork, you get lots of intensity but lousy columnation. Back the bulb across the room and you get columnation and no intensity. Somewhere in between (probably 16" to 30" depending on the quality of the reflector) is what you want, but you'll have to experiment a bit to find it.

It looks like I'll be buying some lamps. What should I look for or look
out for in florescent types?
