Owing to the excellent dispersion ability, diffraction gratings are playing an important role in widespread fields ranging from spectrometers to chirped pulse amplifiers. However, decades of extensive ...

Fibre optics is now the fastest and most reliable technology to deliver internet connection. Data is transmitted through fast-travelling pulses of light that bounce off the walls of the fibre cables ...

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 ...

This white paper details how compact spectrometers based on transmission gratings can provide important benefits such as a high throughput for low light applications, flexibility for OEM integrators, ...

(Phys.org) —A new kind of x-ray multilayer grating that could open a pathway for high-sensitivity, hard x-ray phase contrast full-field imaging of large samples has been developed by researchers at ...
