The geometry for calculating the maximum scattering pathlength difference. With the values y = 1.75 mm, t = 5.32 mm, z = 1.5 m and w = 20 µm, the maximum pathlength difference is given by t + BP − AP = 2.7 × 10−8 m. The calculated longitudinal coherence length is [\lambda^{2}/2\Delta\lambda] = 5.9×10-7 m.
