Optics and Optical Design - Optical Ray Diagrams versus Paraxial Ray Tracing: Solving a Two-Lens Imaging Problem Both Ways

Ray diagrams and ray tracing are two different approaches to solving imaging problems. One involves sketching the principal rays using known focal lengths. The other involves computing the refraction of the principal rays at each surface. A two-lens problem using one converging and one diverging lenses is solved by both approaches.
