on today's installment of parts that terrify me:

I don't actually know much about this LED, but it's certainly a very strong, possibly ultra low wavelength UV led. The incredibly clear cover-glass and the fact that the dies are water-cooled give off an eerie vibe.

I’m actually scared of figuring out the output power and wavelength by hooking it up to a lab supply. Anyone who knows what specs this could have? What part no it could be?

another glamour shot, I should do a focus stack! Also this device is both tiny and way too large at the same time, it’s also quite heavy!

so, that LED is likely a 405nm 9W led. Thats not too terrifying actually, not even really UV light! We can do better, how about this device

It has two 6W light sources, one emitting at 366nm, that’s certainly UV! UV-A to be precise.

The other tube however has its peak at 254nm, UV-C light. Now, that’s scary!

or even better, how about this bare Deuterium arc lamp. Its spectrum starts at 112nm and is continuous from 180nm. Thats almost covers the whole UV region, bordering into the Extreme UV/EUV region (<121nm).

This thing is really really scary and I will likely never turn it on. Looking down it’s "eye" (second photo) is fun though…

@janamarie I want a deuterium lamp! my spectrometer has a halogen light source on it currently but that tops out around 350-400 nm so while the detector is sensitive down to 200 I can't actually do useful transmission measurements that low

@janamarie the vendor had a deuterium option available for it but it was $$$$ and i had no immediate need so i didn't buy it

@janamarie Given how much stray light leaks out from around the halogen lamp housing, I'd definitely be wearing my good eye pro while running it lol

@azonenberg oh, you can 100% have it! I would have thrown it out/trashed it some time anyways… it has an unknown runtime though

@janamarie If it's a bare lamp and not fiber coupled it's not useful to me and I don't have the time or skill to do the optical design to make it so.

Just drooling about the idea of eventually having one

@azonenberg damnit, almost got rid of it :p

@janamarie Instead of throwing it in the trash, may I have the D2 lamp? I have an UV spectrophotometer that is missing its lamp and the holder on yours looks like it might fit...
Show threadJanaFeb 26
@stdlogicvector sure! (dw though, I wasn't going throw it out anytime soon, but I literally have zero use for it, so I would love for it to find some use!!)
