The stage micrometer slides are prepared slides that contain a tiny ruler beneath the coverglass. The rulers on these particular slides are two millimeters long and subdivided into smaller increments. Place the stage micrometer slide on the stage of your microscope and locate and focus on the ruler as directed in the lab manual. Measure, or estimate as accurately as possible, the distance across the diameter of the field of view. Record the value to the nearest tenth of a millimeter for scanning, low, high and oil immersion lenses.
