  • the thickness of lens 10 decreases as you move away from the center, and the angle of incidence and refraction of light increase. Furthermore, spherical aberration also increases as you move away from the center. However, since Figure 3 is a cross-sectional view for explanatory purposes, the spherical aberration of lens 10 is ignored. The same applies to Figure 4 and beyond.
