SPECTROSCOPY FEATURES
Advancements in Diffraction Grating Aim to Change the Rules Jul 25, 2022 — Because they separate light into its spectral components, diffraction gratings lie at the heart of modern spectrometers, hyperspectral imagers, optical coherence tomography systems, and similar instruments. In the future, gratings may improve automotive lidar, a market that could reach tens of millions of units annually. Gratings have also played a role in reducing the footprint of spectrometers in the last few years, vastly expanding their market by enabling more compact and mobile devices.
