on a similar note, if you do anything with lasers, pleaseee get proper laser glasses. I know they are expensive, but you absolutely do not want to burn your retina, don't play with that shit. I'd highly recommend https://www.noirinsight.com/ as a supplier, they are very reasonably priced and trustworthy. I am also pretty sure they are the OEM for thorlabs.

@MissingClara My Thorlabs LG1B are NoIR for sure, haven't checked the rest of their lineup but it woudln't surprise me

@MissingClara you make it sound like there's only one. I know of... too many these days

@MissingClara (I don't actually work with any super high power lasers currently but i have some very strong non-coherent UV sources and i figured that while overkill, laser rated eyewear would definitely get the job done)

@MissingClara like 1W of 365 nm or thereabouts. Optical power not electrical input

@azonenberg yeah, I have a Continuum Minilite II, which I want to put on a Mitutoyo FS-60 head, for laser ablation. at 532nm, it does 25mJ in 3ns, which is... uh... scary

@MissingClara what's that in megawatts I'm too sick to do the math in my head

@azonenberg yeah, ~8MW peak power, and it can do it up to 15Hz. even stray partial reflections can be blinding. I see people using these kind of sources with regular frame glasses, and it freaks me the tf out. I have some NoIR DBY-60, which are the wrap around style. the DBY filter also covers all of the Nd:YAG harmonics, in case any somehow leak out 🙈

@MissingClara yeah LG1B are more conventional glasses type but I'm working with an incoherent CW source so not really that worried about reflections other than like a direct specular reflection off a solder joint at my face

@azonenberg right, I think those are fine there

@MissingClara i would definitely be concerned about 1064 leakage with any of the doubled/tripled systems. At megawatt power levels even a fraction of a percent of leakage at the other line is a lot lol.That's the kind of levels where I'd want like interlocks on the door to the room and everything

@azonenberg yeah, I am gonna wire redundant interlocks on the door, and put signage outside. I'll probably have a dedicated room for it, and my uh spicy light cabinet.
