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 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 ...

Wavelength dispersive X-ray Fluorescence system for accurate elemental analysis ... Standard-less analysis capability Parallel beam X-ray diffraction system for investigation of phase assemblage of ...

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.

This interaction produces a diffraction pattern that is characteristic of the sample's structure. The principle of operation for XRD involves the Bragg's Law, which relates the wavelength of the ...
