The result of the final analog electronics project is presented, which consists of a machine with the ability to detect the focus of a converging lens. The device employs a method designed by implementing classical theories of physics, in this case geometric optics, in order that in the future this method will be used to find the focus as precisely as possible, allowing to analyze and demonstrate geometric optics.
