WebThe thin lens formula , 1/f = 1/v + 1/b (see diagram below), is often used to model how a 35mm camera lens works. But what is rarely understood is how to properly measure 'v' and 'b' for a thick lens. Almost always, the measurements are large enough that errors caused by misuse of the formula are negligible and not even noticed.
