Examples
“For p = -1, the values of q giving minimum spherical aberration (q = 0.71) and zero coma (q = 0.8) are approximately equal to each other.”
“If the refractive index is low, the minimum spherical aberration is not greatly affected by the fact that the second lens operates in a converging beam, and the spherical aberration is approximately equal to h⁴K³.”
“Conventional spherical intraocular lenses (IOLs) have⟳ positive spherical aberration.”
