Abstract

We study the formation of the caustic surfaces formed in both convex-plane and plano-convex spherical lenses by considering a plane wave incident on the lens along the optical axis. Using the caustic formulas and a paraxial approximation we derive analytical expressions to evaluate the spherical aberration to third order. Furthermore, we apply the formulas to evaluate the circle of least confusion for a positive lens.

摘要

我们通过考虑沿光轴入射到透镜上的平面波，研究在凸面 - 平面和平凸球面透镜中形成的焦散面的形成。利用焦散公式和傍轴近似，我们推导出用于评估三阶球差的解析表达式。此外，我们应用这些公式来评估正透镜的最小弥散圆。
