From Cleo Abram.

These are some of the smoothest, most reflective mirrors in the world!

They’re polished to have bumps just a few atoms thick! They reflect 99.9999% of the light that hits them, but they’re not FOR visible light!

They’re made to reflect light from an infrared laser that’s part of the most precise experiment humans have ever built.
