Grating linear
WebSep 1, 2024 · A reflective grating is traditionally made by depositing a metallic coating on an optic and ruling parallel grooves in the surface. Reflective gratings can also be made of epoxy and/or plastic imprints from a master copy. In all cases, light is reflected off of the ruled surface at different angles corresponding to different orders and wavelengths. Webθ. r. A diffraction grating is created by a spatial modulation in phase or amplitude of an incoming plane wave. When exiting the grating, the input is separated into several plane …
