Microscopes can be used not only to look at small things but also to measure them. Items seen in microscopes are very small, even a few millimeters are too big. As a result, micrometers are used. The micrometer is divided into ocular micrometer and stage micrometer, and two kinds of micrometer are used together.
an ocular micrometer is a glass disk with ruled scale on the surface which is etched in chromium.
