Today, astronomers seek to observe the faintest and most distant objects possible. Extremely Large Telescopes (ELTs), with apertures in the order of several dozen meters, are the next generation ...

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), please contact us at ...

Holographic and Ruled diffraction gratings are available from Optometrics for use in high-level spectroscopy, alongside our Echelle, Filtered and Transmission gratings. One of the few gratings ...

A laser pointer shining on a diffraction grating or CD creates a series of diffraction spots depending on the spacing of the lines or pits in the grating or CD and the wavelength emitted by the laser.

Sunlight appears white because it is a mixture of countless colors of light, so when light is reflected in a way that breaks down that white light, it appears rainbow-colored. When white light is ...

Diffraction gratings are curious things. Score a series of equally spaced tiny lines in a surface, and it will cause reflected or transmitted light to bend and separate into its component wavelengths.
