It states that the uv lamp wavelength is 234 nanometers
If not ,what shall I use as an economic source for uv???Fleaker - 3-6-2008 at 17:35
NERV is working on an easily made 100W UV bulb from a cheap commercial mercury vapour lamp. He plans on using it for his TLC plates and for
photohalogenation.Magpie - 3-6-2008 at 17:48
Take a look at the 100w mercury vapor security lamp I reassembled:
Those aquarium lamp would be just perfect. But a cheaper options are the "eprom erasers" sold in informatics places (i have no idea of what an eprom
is, and why you would want to erase the poor thing with UV ), where they sell
equipment to etch your own boards circuits. Some small models are very cheap, and work perfect with 254nm TLC plates.
I made myself a little wooden box to insatll th etube with a ballast and satrter and all, and protect myself from the UV's, but with a space to slide
the plates and see/mark the spots without been exposed. Cost me 15E at most!
OT: EPROM

Roughly speaking, an EPROM is a silicon chip consisting of CMOS circuits and insulated gates which store charge representing on and off states.
Essentially, by shining ionizing radiation on the chip, these charges are momentarily shorted out and the EPROM is erased. You may've seen one
before, as the foil or tape covering the glass window is distinctive among integrated circuits.
Back on topic, it's fortunate, then, that they need such ionizing radiation, eh?

Thank you for the explanation! Indeed, it's then a good thing to irradiate the little buggers Beware, eproms, here we come (i can't help
picturing them like those little fury bears in Starwars, forgot their name)
Sorry for the off topic, couldn't resist
