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.

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 ...

For thousands of years, thinkers argued about whether light is made of particles or waves. At the beginning of the 20th ...

Particle size analysis is crucial to quality control and product development in a number of key industries including aerosols, construction, food and beverage, paint and coatings, and pharmaceuticals.

Diffraction occurs when a wave encounters an obstruction in its path and will change direction, or wrap around it. In ocean waves, we see this occur when a wave encounters an object like a jetty and ...

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 ...

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 ...

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 ...

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 ...
