The utility of transmission measurement has made it a target for quantum\nenhanced measurement strategies. Here we find if the length of an absorbing\nobject is a controllable variable, then via the Beer-Lambert law, classical\nstrategies can be optimised to reach within 83% of the absolute quantum limit.\nOur analysis includes experimental losses, detector noise, and input states\nwith arbitrary photon statistics. We derive optimal operating conditions for\nboth classical and quantum sources, and observe experimental agreement with\ntheory using Fock and thermal states.\n
