Lens Makers Formula: Definition, Concepts and Examples - Toppr
A lens is said to be thin if the gap between the two surfaces is very small. A lens will be converging with positive focal length, and diverging if the focal length is negative. So we can conclude that a convex lens need not necessarily be a converging and a concave lens diverging. Learn lens makers formula.

The two spherical surfaces of the lens have their centres at C 1 and C 2. The optical centre is at P and the principal axis cuts the two spherical surfaces at D and E . As shown in the figure, after the first refraction image is formed at O 1 and after second refraction the final image is formed at I .
