Lens Maker’S Formula For Thin Lens The lens maker’s formula involves the focal length, refractive index of the material of the lens and the radius of curvature of the two surfaces of the lens. This formula is derived from the refraction of light on the two spherical surfaces of a lens....
From the above formula for the power of the lens, we understand that the power of a lens is the reciprocal of the focal length (which we calculate in metres). Lens power is measured in dioptres (D), which is also equal to 1/m. Converging (convex) lenses have positive focal lengths,...
