A device for measuring very small distances, angles, or objects, especially one based on the rotation of a finely threaded screw, as in relation to a microscope.

First recorded in 1660–70; micro- + -meter

A one-half inch eye-piece, a micrometer eye-piece, and an attachable mechanical stage are very useful additions.

Focus the scale of each micrometer accurately, and make the lines on them parallel.

Place a stage micrometer divided into hundredths of a millimetre on the microscope stage and focus accurately.

Rotate the head of the micrometer screw until the movable line has transversed one division of the stage micrometer.

Note the optical combination employed in this experiment and record it with the calculated micrometer value.
