WebMar 6, 2024 · As others pointed out, the lensmaker's formula describes how the object p and image q distance are related to this property of the lens. So you just measure p and q, and find f from f = p ⋅ q p + q (I took the liberty of rearranging the usual formulation 1 f = 1 p + 1 q so you obtain f directly from your measured values).
