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 ...

Chromatic dispersion management is one of the most important technologies for high-bit-rate DWDM systems. In particular, the transmission quality in 40Gbit/second systems is highly sensitive to ...

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 ...

As stated in the article titled ‘An Introduction to a Spectrometer: The Slit’, a spectrometer is an imaging system that maps a plurality of monochromatic images of the entrance slit onto the detector ...

THE June issue of the Journal of the Franklin Institute contains two interesting letters from the second volume of the Transactions of the American Philosophical Society (1786), from which it would ...

Visual demonstration of the performance of the diffraction grating. The zeroth order transmission refers to light that goes straight through the grating without undergoing diffraction (which should be ...
