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
What camera?

You can remove the hot mirror from the sensor and put back some clear glass like a cut microscope slide.

I used to DIY my Full Spectrum conversions before finding KolariVision Infrared.

Currently only two phone cameras. I'd have to buy them hence why I ask...

@agowa338
Have any webcams at least? Usually really simple construction to remove the hot mirror.

@Brett_E_Carlock Yea, but none that is nearly good enough. Just quite shitty ones. Also I'm not even sure there is a mirror inside.

Probably like @nantucketlit says just a filter or something.

@agowa338
Hot mirror is not a mirror like in a reflex camera. It is the specially treated glass over the sensor that bounces UV and IR.
