WebParaxial grating behavior for coarse gratings (d ≫ λ) is then derived and displayed graphically for five elementary grating types: sinusoidal amplitude gratings, square-wave amplitude gratings, sinusoidal phase gratings, square-wave phase gratings, and classical blazed gratings. Paraxial diffraction efficiencies are ... WebWe considered comparative modeling action of a hyperspectrometer based on the Offner scheme including prisms or a diffraction grating within the geometrical optics. It is shown that the use of a diffraction grating instead of a prism results in a more uniform spread of the spectral components of the dispersed image.
