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?
@janamarie watercooled led

@jasper not really, could be a TVS diode
@janamarie @jasper I guess it is rather something to measure temperature

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 how to Hautkrebs fast

@janamarie we borrowed a UV lamp sort of like that for curing a countertop and it was terrifying

@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
