WebEssentially, the thick lens is described as having 2 planes of focusing power, separated by a finite, fixed distance. For purposes of finding/using lens power values, distance to the object is measured from one plane, and distance to the image is measured from the other plane. WebJul 22, 2024 · Then, using the thin lens equation, we find that a real, inverted image is formed at a distance $2 f$ from the lens. \begin{equation} \frac{1}{2 f} + \frac{1}{2 f} = \frac{1}{f} \end{equation} Geometrical optics also says that when the screen is placed on the focal point of the lens, it should display a single point, where the thin lens is ...

WebDec 18, 2024 · Here’s the thin lens formula: 1f=1dₒ+ 1dᵢ The trick is to know when these are positive and when they are negative. f is the focal length. When you have a thin lens, there’s a focal point on both sides. The focal length is calculated as the distance from the center of the lens to the focal point (on either side).
