Q: What are diffraction gratings? A diffraction grating is an optical component for spectroscopy that splits light into different wavelengths. A typical diffraction grating has thousands of ...

In particular, it is possible to obtain theoretical 100% diffraction efficiency with one linear polarization at ... This reduces the total beam deviation and reduces the air‐to‐glass incidence angle ...

However, using an atom-thick layer of carbon atoms known as graphene, experts found that even after 100 hours under irradiation of an atom beam, the grating showed no damage and diffraction still ...
