Dispersion | Edmund Optics

Chromatic dispersion is a dependence of light’s phase velocity ν p in a medium on its wavelength, resulting mostly from the interaction of light with electrons of the medium. Chromatic dispersion is described by the Abbe nuer (Figure 2), which corresponds to the reciprocal of the first partial derivative of refractive index with respect to λ, and partial dispersion, which corresponds to
