And you can get, say, 200 nanometer optical resolution, which is good, which is really good.
So that's the situation with an optical achromatic lens.
Now, x-ray chromatic lens, achromatic lens, that could focus to 20 nanometers.
So in order, you have an order of magnitude greater optical resolution.
You could zoom in on stuff and see amazing details with it.
And you could also, it's x-ray.
You could see inside, in some substances, you can see inside it as well.
So this is, you know, an amazing imaging technology that you could use.
Yeah, yeah.
Pictures, high-resolution images of the nanoworld, the microworld, the really small images, high-resolution images of tiny things that optical imaging can't really do.
So 200 nanometers to 20 nanometers.
So nanometers, billionth of a meter, super tiny.
That's hugely more sharper.
It would be a great tool, but we don't have an achromatic.
Why am I looking at them?
There's no achromatic X-ray lens.
They don't exist, and that's because they couldn't find two materials that you could then stick together that are different enough that could disperse the x-rays and then focus them down.
Those two materials, like the concave and convex lens, they didn't exist.
So what you had to do, if you wanted to take a high-resolution x-ray
image, you'd have to go to a lab or something, go to a synchrotron, which is basically a super bright x-ray source, very, very bright, and then you would use that and you would take your image, but then you would have to filter out all those frequencies that were outside of your plane.
