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?

A photo of a complex metal casing with a golden window with a circular array of small dies and bond wires. It rests on a grey mat and looks expensive

Photo of the back of the case. It rests on a glass slide and the mat. Two outlets that look like luer lock hint at this device consuming a lot of power, it’s a water cooling circuit

A closeup of the array of dies. It’s 21 small dies that each have a small array of four by four squares in them. A bunch of golden bond-wires escape to the side where they connect to a golden ring. The golden ring is isolated from the golden backplate by another white ring

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!

A slightly angled closeup of the die array. You can clearly see the die’s structures and the bondwires escaping to the side. It’s a beautiful golden clean housing

The led held by my gloved hand. It gives a size relation, it is just slightly larger than my thumb
