Spherical cylindrical lenses

WebA spherical surface is one that has each point on it at the same distance from a point. A thin slice of a sphere is a circular plano-convex lens. A circular cylinder ( there are other cylinders, like elliptic cylinder etc) is a surface where each point of the surface is equidistant from a fixed line.
