Lens maker formula questions. SF017 SF027 51 15 Thin Lenses Formula and Lens makers Equation Considering the ray diagram of refraction for 2 spherical surfaces as shown in figure below. Consider a convex lens or concave lens of absolute refractive index m 2 to be placed in a rarer medium of absolute refractive index m 1. You have to use the lens makers equation 1f n2n1 1 1R1 1R2 where f is the focal length of the lens R1 and R2 are its radii of curvature n2 is its refractive index and n1 is the refractive index of the medium in which the lens is placed.
