WebFor combinations of two thin lenses in contact, we have seen that the focal length of the combi- nation is given by an expression involving the individual focal lengths: 1 f = 1 f 1 + 1 f 2 (4) Combinations of two thin lenses can be used to make an extremely important optical device: the refracting telescope. WebA ray through the center of the lens, which will be undeflected. (Actually, it will be jogged downward on the near side of the lens and back up on the exit side of the lens, but the resulting slight offset is neglected for thin lenses.) A ray through the principal focal point on the near side of the lens.
