WebApr 8, 2024 · 1 f = n ′ − n n ( 1 R 1 − 1 R 2) R 1, R 2 are the curvature radii of the surfaces of the lens. n ′ is the refractive index of the interior of the lens, whereas n is the refractive index of the medium outside the lens. So for n ≈ 1 (lens in air) you get 1 f A i r = ( n ′ − 1) ( 1 R 1 − 1 R 2) Hence, f f A i r = ( n ′ − 1) n n ′ − n
