Several approaches are capable of beating the classical 'diffraction limit ... a schoolboy will be able to screw a nano-array lens to his science class microscope and see a DNA molecule.

The aluminum is polycrystalline so that the diffraction pattern consists of rings. The graphite consists of small crystallites with the c-axis perpendicular to the surface of the foil so that the ...

It arises due to the wave nature of light and the physical limitations of focusing light through a lens system. The diffraction limit restricts the spatial resolution of optical microscopes, making it ...

“A walking robot that’s small enough to interact with and shape light effectively takes a microscope’s lens and ... nanomagnet arrays and the flexible hinges; the platform can also embed optical ...

This meant that a microscope could not resolve two objects located closer than λ/2NA, where λ is the wavelength of light and NA is the numerical aperture of the imaging lens. This diffraction ...
