Making a perfect lens that produces flawless images has been a dream of lens makers for centuries. In 1873, Ernst Abbe discovered a fundamental 'diffraction limit' in optics: whenever an object is ...

In many industries, laser diffraction is used to perform routine particle size analysis. The power of laser diffraction is such that it has started to replace conventional techniques, such as sieving.

Altermagnets are a newly recognized class of antiferromagnets whose magnetic structure behaves very differently from what is ...

Diffraction spikes, visible in high-power astronomical images, are an intrinsic optical phenomenon in reflecting telescopes, primarily caused by the diffraction and subsequent interference of incoming ...

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 ...

Stars in the new images from the James Webb Space Telescope look sharper than they did before. And I’m not just talking about the image quality, which is astounding. I’m talking about the fact that ...

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 ...

Description: Electron diffraction patterns for single crystal and polycrystalline materials are displayed on a CRT screen. A Welch model 2639 'Electron Diffraction tube' is used in an experiment in ...

When a laser beam is incident on a narrow opaque object such as a fine wire or a strand of hair, the resulting diffraction pattern is similar to the diffraction pattern of a slit of the same width as ...

The diffraction grating of a spectrometer partially determines the optical resolution that can be achieved by the spectrometer and also determines the wavelength range. Selecting the correct grating ...

The author examines the process of method development, with reference to ISO 13320:2009 and relevant monographs from the United States and European pharmacopoeias. Particle size is a critical quality ...
