# Solve Plano-Convex Lens Lensmaker's Equation

• paulstgeorge
In summary, the Lensmaker's equation for a plano-convex lens can be simplified to the formula shown in simple2.jpeg by letting the second radius go to infinity. This results in a number of terms becoming zero, regardless of whether one starts with the formula shown in simple1.jpeg or complex.jpeg.

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!

Let the second radius go to infinity.

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.
