WebIn 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 … WebAug 6, 2024 · The thin lens equation describes how the image of an object after crossing a thin lens is created. This approximation considers that the width of the lens is much smaller than the object's distance. To use it, we only need the focal length and the object's distance: \frac {1} {x}+\frac {1} {y} = \frac {1} {f} x1 + y1 = f 1 where:
