That was only true for early tools. The AIMS system Zeiss has proposed uses direct EUV imaging, similar to the prototype SEMATECH Berkeley Actinic Inspection Tool (AIT).

If I recall correctly, EUV AIMS used an intermediate EUV-to-photoelectron converter, and it is the photoelectrons which are imaged. Normally (for DUV), a microscope CCD set up would suffice. It suggests purely relying on EUV optics would be too expensive.
