Optical axis center
WebThe ray directed parallel to the optical axis refracts through F on the far side. The ray directed to the near F refracts parallel to the optical axis. The ray directed to the center of the lens is undeviated (in the thin lens approximation). The ray diagrams for two cases of a converging lens are shown in Figure 18. WebOct 26, 2024 · The paraxial approximation can be used to derive simple equations involving lenses. A statement of the approximation involves the optical axis, which is a line that passes through the center of each lens and is oriented in a direction normal to the surface of the lens (at the center). The paraxial approximation approximation is valid for rays ...
