The lensmaker's equation, 1 p + 1 q = 1 f is all you need if you have p and q. Just solve it for f, which is the focal length (the distance from the lens to the focal point). WebI have found the formula for the effective focal length f of two thin lenses with focal lengths f 1 and f 2 separated by distance d to be 1 f = 1 f 1 + 1 f 2 − d f 1 f 2. However, I can't seem to find how f is defined. Is it the distance from the first lens to the final focal point or the distance from the second lens to the final focal point?
