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.
