|Toolmaker's microscope with digimatic measuring heads.|
Toolmaker's microscopes are available with manual measuring micrometer heads, as shown below, or with digimatic micrometer heads. The manual micrometer heads are less expensive and provide measurements in either mm or inches. Measurements are made by positioning the sample in the center of the cross-line reticle in the microscope, then turning the micrometer (which controls the stage) until the edge of the part lines up with the crossline. The micrometer head measures the distance the stage moved.
