Ruled grating equation
WebbGenerally several integers m will satisfy the grating equation – we call each of these values a diffraction order. 2.2.1. Existence of diffraction orders. For a particular groove spacing d, wavelength λ and incidence angle α, the grating equation (2-1) is generally satisfied by more than one diffraction angle β. WebbThe grating’s resolving power (R) is dependent on the spectral order (m) and the number of grooves under illumination (N): (2)R = λ Δλ = mN R = λ Δ λ = m N There are often so …

WebbThe grating equation mλ=d (sinα + sinβ) can be differentiated to give the angular spread (dispersion) of the spectrum: Here α and β are the angles of incidence and diffraction, m is the diffraction order, λ is the wavelength and d is the groove spacing. Figure 1. WebbGeometric theory of the grating is developed, with special emphasis on the relation between the properties of holographic gratings and those of mechanically ruled gratings. The theory is applicable to practically all types of holographic and mechanically ruled gratings, including aspheric gratings. General expressions are given for the effective …
