Measuring with the microscope - ruf.rice.edu

A stage micrometer is simply a microscope slide with a scale etched on the surface. A typical micrometer scale is 2 mm long and at least part of it should be etched with divisions of 0.01 mm (10 µm). Suppose that a stage micrometer scale has divisions that are equal to 0.1 mm, which is 100 micrometers (µm).
