A typical diffraction grating has thousands of grooves per millimeter on the reflective surface of a plate that can be flat or curved. Different gratings cover various electromagnetic radiation ...

Reflective ruled diffraction grating is a kind of optical glass substrate composed of dense, equidistant parallel lines, and the surface is coated with aluminized, multi-layer dielectric or other ...

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 ...

ABSTRACT We discuss the polarization properties and first‐order diffraction ... boundaries give higher reflection losses (for unpolarized light). Here we give the equations for calculating the ...

Sure, a hacker could make one if he or she put their mind to it. But make one out of a webcam, some cheap diffraction grating purchased off ebay and some scrap? Surely not. [Renaud] pulls off this ...
