In other words, aberrations are imperfections of optical systems. They are not caused by defects in the making of devices but rather because of their physical conditions.

For lenses made with spherical surfaces, rays which are parallel to the optic axis but at different distances from the optic axis fail to converge to the same point. For a single lens, spherical aberration can be minimized by bending the lens into its best form. For multiple lenses, spherical aberrations can be canceled by ...
