Descrição: We first examine the dispersion in wavelength units (nm/pixel). The dispersion curve for the 600-g/mm grating over the entire range shown (200-1775 nm) is almost flat, varying between 0.144 and 0.138 nm/pixel. On the other hand the behavior of the other grating is quite different. For all values of X > 1080 nm, the dispersion is pinned to 0 nm/pixel. At these long wavelengths, a grating with this value for the groove density will not diffract.
