An example figure from the Ray Diagram Generator.

A ray diagram of a converging lens with F, F′, 2F and 2F′ marked, an object O beyond 2F, three principal rays, and a real, inverted, smaller image I between F′ and 2F′ — A converging lens of focal length 10 cm with an object 4 cm tall, 30 cm away, beyond 2F. Three principal rays leave the object’s tip: parallel then through F′, straight through the center, and through F then parallel. They meet between F′ and 2F′, where the real, inverted, smaller image is drawn.
