    Solve Plano-Convex Lens Lensmaker's Equation

    Thanks. Does that mean the formula is simplified to the formula shown in simple2.jpeg? Whether I start with the formula shown in simple1.jpeg or that shown in complex.jpeg, if the second radius is infinity a number of terms are then zero.

    Solve Plano-Convex Lens Lensmaker's Equation

    Can someone help me with the Lensmaker's equation for a plano-convex lens? The formula for a bi-convex lens is readily available but it includes a term for the radius for each of the two curves. A plano-convex lens has only one radius!
