The refractive index variation for pure silica in the wavelength region 0.5 μm < λ0 < 1.6 μm is accurately described by the following empirical formula

where C0 = 1.4508554, C1 = – 0.0031268, C2 = – 0.0000381, C3 = 0.0030270, C4= –0.0000779, C5 = 0.0000018, l = 0.035 and λ0 is measured in μm. Calculate and plot n(λ0) and d2n/dλ02 in the wavelength domain 0.5 < λ0 < 1.6 μm.
