Fig. 6.

Measurements from λ = 450 nm to 850 nm of (a) the absorption coefficient μ_a and (b) the reduced scattering coefficient ${\mu }_s^{\prime }$ of the three the B0430 samples (nominal thicknesses t = 5 mm, 7 mm and 10 mm). Continuous lines are used to represent the upper and lower bounds of the uncertainties on the results by the single integrating sphere measurements. The results are compared to measurements by INO at λ = (475, 540, 543, 630, 632, 780, 805 and 850) nm (uncertainty at k = 2).
