WebSep 12, 2024 · These equations, called the thin-lens equation and the lens maker’s equation, allow us to quantitatively analyze thin lenses. Consider the thick bi-convex lens shown in Figure 2.5.8. The index of refraction of the surrounding medium is n 1 (if the lens is in air, then n1 = 1.00 ) and that of the lens is n2. WebThin lens approximation. For a thin lens in air, the focal length is the distance from the center of the lens to the principal foci (or focal points) of the lens.For a converging lens (for example a convex lens), the focal length is positive and is the distance at which a beam of collimated light will be focused to a single spot. For a diverging lens (for example a …
