Stage micrometer divisions as seen under microscope. It is used to calibrate the ocular micrometer. Smallest division = 0.01mm or 10 microns.

An ocular micrometer or eyepiece micrometer is a glass disk, engraved with a ruled scale, that fits in an eyepiece of a microscope,[1][2] which is used to measure the size of microscopic objects through magnification under a microscope. When the eyepiece micrometer is calibrated using a stage micrometer, the length of the divisions on the scale depends on the degree of magnification.[3]
