Propose a method for evaluating the measurement uncertainty of magnification error in metallographic microscope objective lens. Establish a measurement uncertainty evaluation model based on calibration methods and analyse the sources of each uncertainty. Combining measurement examples, this article elaborates on the evaluation of uncertainty in the measurement of magnification error of metallographic microscope objective lens.
