on today's installment of parts that terrify me:
-
@janamarie any idea what the small separate die in the bottom right is?
@jasper not really, could be a TVS diode
-
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!
Is it cold to the touch?

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 This looks suspiciously like the 405nm 9W LEDs this person posts about? (first attachment)

@janamarie And not to miss the point here: what a gorgeous and terrifying hunk of Technology! Thank you for sharing

@janamarie watercooled led

@janamarie @jasper I guess it is rather something to measure temperature

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 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
