Advice on how to calibrate an optical (compound) microscope objective lens using a 10mm stage micrometer. Please note that the calculations in this video are for the 10mm stage micrometer but some college labs use a 1mm stage micrometer. If you use the latter type you will have to adjust your calculations but the method is exactly the same.
