M. G. FOUSSERAU describes, in the Journal de Physique for October, a simple apparatus for viewing diffraction and interference phenomena, a modified form of which I have experimented on with success.

The Grating Challenge. This page contains hints, solutions, and advanced challenges for our diffraction grating challenge. If you would like a grating (or a set for your class if you are a teacher), ...

A new publication from Opto-Electronic Advances, 10.29026/oea.2023.230039 discusses diffraction-limited visible imaging for large aperture telescopes.

Optically controlled dense current structures driven by relativistic plasma aperture-induced diffraction. Nature Physics , 2016; DOI: 10.1038/nphys3613 Cite This Page : ...

Place the aperture on the optical rail. Plug in the laser and aim it at the slit. Adjust the size of the aperture such that the Fraunhofer diffraction pattern is visible. Use the lab jacks to elevate ...

The diffraction limit arises from the wave nature of light and the principles of diffraction. When light passes through an aperture, such as the objective lens of a microscope, it undergoes ...

Plug in the laser and aim it at the aperture, make necessary adjustments such that the intended diffraction pattern is visible. The aperture should be very close to the laser to maximize the incident ...

I learned in October 2022’s Breakthrough that the spikes of stars in high-power photos are called diffraction ... (or aperture) and the number and orientation of secondary mirror struts ...
