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
As a wild guess, could be the LED for a LED-pumped Nd:YAG fiber laser. Never actually cracked one open but the construction, water-cooling, and general vibes are all about right. -
@PeterSommerlad @janamarie wrong conference I'm speaking at https://harris2026.mpi-sp.org/
But if you're in the area and want to say hi, by all means
too much of a software guy to be aware of this event. unfortunately i am booked all Saturday and returning on Sunday.

@PeterSommerlad @janamarie then we won't overlap anyway my flight lands DUS around 5pm Saturday so by the time i get to bochum it'll be late

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!
@janamarie this looks like it may just be a very high power white module, but may also be a UV curing module. Either way, this is definitely in the 100W+ class and you do NOT want to look into it either way. Or operate it without water (distilled only) for even a MINUTE.

@janamarie And to be turned on when on the proper heatsink and not in line with your sight - being it in the visible range or not.

@janamarie Looks like the last thing one would see

@janamarie Demon Core (pocket edition). 🫣

@janamarie any idea what the small separate die in the bottom right is?

@jasper not really, could be a TVS diode

Is it cold to the touch?

@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…
