The relation between the allowed range of variation of polarization controller wave‐plates angles and the respective polarization scattering properties is investigated. It is demonstrated that a nearly uniform polarization scattering over the Poincaré sphere is obtained using a concatenation of three polarization controllers with angles randomly changed between ‐π/4 and π/4. It is also shown that an improvement of the scattering properties is obtained if the configuration angles are allowed to change between ‐π/2 and π/2.
