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.

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 ...

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 ...

“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 ...
