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 ...

This limit is typically about one-half to one-quarter of the wavelength of light involved. Now three independent groups of researchers have shown that it is possible to shatter this diffraction ...

The diffraction limit restricts the spatial resolution of optical microscopes, making it challenging to observe structures smaller than approximately half the wavelength of the illuminating light.

The extent of the spreading (diffraction) depends on how the width of the gap compares to the wavelength of the waves. The wavelength is unchanged after diffraction. A gap width similar to the ...

Electron diffraction is a powerful analytical technique used to study the atomic structure of materials. It involves the interaction of a beam of electrons with a crystalline sample, resulting in a ...

The Materials Research X-Ray Diffraction (XRD) Facility at the University of Colorado Boulder provides cutting-edge capabilities for probing the structures of materials such as polymers, biological ...

which is beyond the diffraction limit. The device also supports optical surface imaging by generating evanescent speckles when the incident wavelength is tuned, further expanding its applications.
