Calculated scattering coefficient (µ _s, equation (10)) as a function of optical particle diameter (D. k₀, k₀ = 2π/λ_{0, vacuum}) for increasing volume fractions (0.01, 0.1, 0.2 and 0.3) at three common OCT wavelengths and bandwidths: λ₀ = 850 (∆λ 65) nm, λ₀ = 1050 (∆λ 81) nm and λ₀ = 1300 (∆λ 100) nm. The used refractive index of the medium and silica beads were 1.324 and 1.425 at 1300 nm, respectively. The refractive indices were varied with wavelength and bandwidth for the calculations. The magnitude of µ _s decreases with increasing wavelength, and increases non-linearly with an increase in scattering particle concentration.
