WebJan 17, 2024 · Thin Lens Model Most cameras use a lens to focus light onto the image plane so that enough light can be captured in a short period of time. Lens models can be quite complex, however, we can consider the simplist case, known as the thin lens model. WebJan 1, 2016 · Thin lens model. Consider first a simple “physical” model for a lens, the thin lens model, for the case of a lens whose two outer surfaces are convex and spherical. For simplicity, we assume here that the two spheres have the same radius R.

WebThin lens model assumes thickness is small compared to curvature: 1. Any ray parallel to the axis on one side of the lens passes through the focal point on the other side. 2. Any ray that passes through the center of the lens will not change its direction. This gives rise to the “thin lens equation”…
