3 Analytical calculations Lens maker’s equation: The formula for a lens in vacuum (air): - - = 2 1 1 1 1 1 R R ) n ( f n : index of refraction of the lens material. R 1 : radius of near surface. R 2 : radius of far surface. The near or far surface is with respect to the focal point F . Near side is surface 1, far side is surface 2. The sign of the radius is then defined as + ” if the center is on the far side; “ - ” if the center is on the near side. In this convention, positive f means converging lens, negative f means diverging lens. F near surface far surface
