CALIFORNIA Photographed by Teijo Kobashi is the one governing the resultant focal length of simple lenses used in combination. This is expressed: p fi x f2 f, + f2 d“ Translated from mathematical terms into words, this means that the resultant focal length of a combination of two lenses is equal to the focal length of the first lens multiplied by the focal length of the second lens, which product in turn is divided by the sum of the same two focal lengths minus the distance separating the two lenses. (In this, as in all optical formulas, it is important to remember not to mix values given in inches with those expressed in millimeters.) In this formula "d" is measured as the distance between the nodal points of the two lenses; for ordinary purposes, it is sufficient to consider these nodal points as being located at the center of a lens. For a simple application of this formula, suppose we have two lenses, Page Nine
