The thin-lens equation and the lens maker’s equation are broadly applicable to situations involving thin lenses. We explore many features of image formation in the following examples. Consider a thin converging lens.
Thin lens - Wikipedia
In optics, a thin lens is a lens with a thickness (distance along the optical axis between the two surfaces of the lens) that is negligible compared to the radii of curvature of the lens surfaces. Lenses whose thickness is not negligible are sometimes called thick lenses.

2023年1月16日 · The lens equation tells us everything we need to know about the image of an object that is a known distance from the plane of a thin lens of known focal length.

A thin lens is defined to be one whose thickness allows rays to refract, as illustrated in, but does not allow properties such as dispersion and aberrations. An ideal thin lens has two refracting surfaces but the lens is thin enough toassume that light rays bend only once.

A thin lens has two focal points, one on either side of the lens at equal distances from its center, and should behave the same for light entering from either side. Look backward and forward through a pair of eyeglasses and comment on whether they are thin lenses.

2024年1月30日 · Features of Lens Diagrams. Lens diagrams can be described using the following terms: Principal axis. Principal focus, or focal point. Focal length. The principal axis is defined as: A line which passes through the centre of a lens. The principal focus, or focal point, is defined as:
2.4 Thin Lenses - University Physics Volume 3 - OpenStax
We use ray tracing for thin lenses to illustrate how they form images, and then we develop equations to analyze quantitatively the properties of thin lenses. Consider an object some distance away from a converging lens, as shown in Figure 2.22 .

A piece of glass of finite thickness with two spherical boundaries is a lens. If the thickness of the lens is much smaller than the diameter of the lens, we call it a thin lens. Thin lenses can be converging or diverging.

Figure 4.5.2 – Varieties of Lenses. Tracing a ray through a lens is a daunting bit of geometry, and as always, when a calculation is daunting, we make a simplifying approximation. In this case, the simplifying principle is called the thin lens approximation.
