WebConvex Lens. A convex lens is also referred to as a converging lens since it “converges” light rays that are incident on it. The lens surface is convex in nature. The figure below shows a common biconvex lens used in labs. If a ray of light passes parallel to the principal axis of a convex lens, the refracted ray passes through the focus.
