An echelle grating (from French échelle, meaning "ladder") is a type of diffraction grating characterised by a relatively low groove density, but a groove shape which is optimized for use at high incidence angles and therefore in high diffraction orders. Higher diffraction orders allow for increased dispersion (spacing) of spectral features at the detector, enabling increased differentiatio… WebJan 11, 2024 · The preparation of the data, as well as the analyses were carried out with Matlab (version 2024a, MathWorks, Natick, MA, USA).
