Scientists in Japan have developed a high-resolution X-ray telescope sharp enough to distinguish an object just 3.5 mm wide from one kilometer away, by combining precision mirror-making technology ...

Chromatic aberration, which appears as color fringing due to a shift of focus with wavelength, is an intrinsic property of light focusing. Such stretched foci impair high-resolution imaging using ...

X-ray mirrors are widely used for synchrotron radiation facilities, X-ray free-electron lasers and astronomical X-ray telescopes. The short wavelength and grazing incidence impose strict limits on the ...
