For the curious people, there are no practical refractive materials for x-rays, and mirror shapes have to be 4 times more accurate than equivalent refractive systems for the same diffraction limit.
- pmayrgundter 2y agoDo you know what the objective limits are with current mirrors? They just say that nanometer objectives are not possible with current mirrors, but no measure of SOTA
- nraynaud 2y agono, sorry, the friend who told me all that left the country.
- pmayrgundter 2y agoThanks anyways
