Web1.3 Ray Tracing Rules for Thin Lenses Following what we did for mirrors, we will first discuss the ray tracing rules for thin lenses (see Figure 5 on Page 8). • The first ray (i.e., Ray 1) is drawn parallel to the optical axis from the top of the object. After being refracted by the lens, this ray either passes through the focal point, F, on WebStudy with Quizlet and memorize flashcards containing terms like Two thin lenses, with focal lengths of 25.0 cm and -30.0 cm are placed in contact in an orientation so that their optic axes coincide.

WebMar 10, 2016 · “The definition of focal length is that it's the distance from the optical center of the lens to the image plane when the lens is focused at infinity.” Actually it's not the optical center, it's the image-side principal point. The principal points are coincident with the optical center only in a thin lens, which a photographic lens never is.
