It is impressive for sure, but still a lot of other things are. Mirror arrays on JWST, fusion ignition lasers. Diffraction limited optics aren't exactly last year development either: there's a host of other places across several countries who can match Zeiss for what is essentially bespoke builds. |

Ah yes. No development time involved here at all. They just built it. I don't know what ASML, TRUMPF, Zeiss, and occasionally the Fraunhofer Institute were mucking about for 25 years. Completely boring bespoke build. Bah. Could get it from anyone else by next week. Pick an off-the-shelf coating too and be done.
It's a wonder nobody else is taking a slice of those ~4 billion USD of revenue Zeiss is making off a bunch mirrors for lithography machines each year.
