What is the name of the point where light rays from infinity coverge after passing through a lens?

When parallel light rays from a distant source (effectively at infinity) pass through a convex lens, they converge at a single point called the focus or focal point. This is a fundamental property of converging lenses. A parabola is a curve, not a point. The center refers to the optical center, not where rays converge. Infinity is where the rays originate, not where they meet.
