These are used on the stage of the microscope and provide a simple and reliable means of accurately calibrating eyepiece graticules. A finely divided scale is protected by a cover glass to correspond exactly with the specimen it replaces. The scale is prepared on a glass disc mounted in a metal slide (76 x 26mm) for convenient handling.
Micrometers without a cover glass for use with reflected light and suitable for use with metallurgical microscopes are also available.
