Beyond that, a switch to an even shorter EUV wavelength of around 6.5 nm is possible, potentially improving resolution by a further factor of two. Such a transition is still highly speculative ...

Traditional methods, however, have critical technical limitations, primarily allowing for wavelength tuning in only one direction—towards only shorter wavelengths (blue-shifting) according to ...

We learn about the planets, stars, and galaxies by their light—visible light, and also shorter-wavelength ultraviolet and longer-wavelength infrared light, invisible to the eye but detectable by ...

the scattering of light by particles that are much smaller than the wavelength of radiation. Here's a second component to ...
