In such a design, a free-form surface prism with aspherical coefficients may significantly improve the system’s performance if the coefficients of the free-form surface prisms are well optimized. The using hybrid Taguchi method - robust multi-objective optimization is employed in this study to achieve success in minimizing axial aberration such as spherical aberration and coma aberration. To reduce the efficiency, the best of this experimental group, spherical aberration reduced 1.15%, while the coma reduced 0.62%.
