Going off of what this electron microscope manufacturer says on their website you can read a CD using an optical microscope and you can almost read a DVD.

The limit is apparently somewhere around 500nm and a DVD would need 400nm. So with a bit of optical enhancements it should be possible.

And if you have the ability to put a microscope and a camera into an almost perfect vacuum you probably can go even further (at least considering what e.g. ASML says for lithography with EUV)

Anyone know how to take pictures of UV light?

Kinda want to add a few UV LEDs to a microscope. And because you can't just look through it directly I'd need a camera that can "see" UV for me.

(Note, I'm talking at home "diy" science experiments here. So don't be surprised why I don't just use an electron microscope or something)

@agowa338 Most DSLR's have a filter over the sense to block UV and IR light. If you disassemble the camera you can remove this filter. I have not personally done this before, but this web page has some suggestions: https://www.imagingtheinvisible.com/section838134_344188.html
