And I read that, I'm like, okay, so why is that such a big breakthrough?

I mean, I know what chromatic, achromatic, kind of knows, I know what that word means, but an achromatic x-ray lens, why is that something that is dramatic?

And it really kind of is dramatic.

Now, an achromatic lens or an achromat,

Essentially, it's great for making imagery.

It focuses different frequencies together, either at a point or on a plane, instead of having all the different frequencies kind of disperse out.

I tried to find out if iPhones have it, and they don't.

I mean, you could probably get an attachment, but it basically gives you superior imaging.

So it's really important.

Now, we've had...

achromatic lenses for optical imagery for 200 years.

200 years we've basically had this technology.

And what it does is, I mean, what's happening is that you have two different lenses.

One, say, for example, concave and convex.

You put them together.

The first lens disperses the light, kind of like a prism.

The second lens focuses it all into a point or in a plane.

Whereas without, if you just had the one lens, the different frequencies of light, like the blue would focus here, the red would focus here,

So you wouldn't get a superior image.

So this brings it all to one point.
