Difference Between Concave And Convex Lens 3 Points. A convex lens is thicker in the middle and thinner at the edges. It is also known as Converging Lens.
The crucial difference between concave and convex lens is that a concave lens diverges the light rays that incident on its surface. A convex lens is thicker in the middle than it is at the edges. Convergent action of a convex lens.
A convex lens is also called a converging lens because the parallel light rays moving through it curves inward and touches converges at a position just beyond the lens known as the focal point.
Therefore concentric lenses are sometimes. On the contrary a convex lens has the ability to converge the light rays passing through it. Convex means rounded or curved like the exterior of a circle or sphere. A Concave lens is thinner in the middle and thicker at the edge.
