That Zeiss hardware has a fixed frequency (and wavelength) of the X rays (there are 2 variants, the one with a higher frequency and smaller wavelength has a wavelength close to 0.15 nm). This article is about a tunable high intensity X-ray source, which can be used instead of a huge synchrotron that could do the same thing.
