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 ...

About the size of a small coin, this tiny grating-based spectrometer is ideal for pocket (consumer) spectrometers and handheld instruments. It has a spectral response range of 640-1050 nm and ...

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 ...

SNSPDs have been widely used in various applications requiring single photon detection thanks to their attractive performances. Since SNSPDs are thin films of serval nanometers in thickness, they are ...
