Diffraction refers to the bending of waves, such as light, when they encounter obstacles or pass through small openings. The size of the opening relative to the wavelength of light influences the ...

Abstract: The essentiality of diffraction wavefront in structural mapping has been perceived, mainly because of its imaging potential for small structural variations and microscopic discontinuities.

What is the Diffraction Limit? The diffraction limit is a fundamental barrier in optical microscopy that sets the minimum size of features that can be resolved using conventional light microscopes. It ...

Optical dispersion occurs when the refractive index of a material changes with the wavelength of incoming light. This variation causes different colors to move at different speeds in transparent media ...

They say seeing is believing but our understanding of chemical systems predominantly depends on second-hand observations and measurements. A colour change can suggest that a reaction has occurred, NMR ...

Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals. These metrics are regularly updated to ...

Light scattering as the basis for size determination of many objects has been explored for a long time. It was Gustav Mie, author of the Mie Scattering Theory, who studied gold nanoparticles in ...

Diffraction gratings are beautiful things, bending transmitted and reflected light and splitting it into its component wavelengths to create attractive iridescent rainbow patterns. It’s the same ...

Laboratory-based diffraction contrast tomography (DCT) was applied to heat-treated lean duplex stainless steel (DSS) to observe microstructural changes by hydrogen infusion treatment. The feasibility ...
