Calibrating micrometers: For quick reference the supplied test piece can be used. For calibrating a micrometer, gauge blocks are used.
Stage micrometer is a glass slide with a scale of known divisions used to calibrate the eyepiece micrometer. Ocular micrometer is a specialized eyepiece with a built-in scale used to measure the size of objects viewed under a microscope. They both help determine the magnification and size of objects but are used at different stages in the setup process.

A stage micrometer is used in microscopy to calibrate the eyepiece reticle or camera system. It provides a known distance for calibration, allowing accurate measurement of objects viewed under the microscope.
(the metric unit) The average bacteria is only about a micrometer in length, so there may be thousands in a single drop of water. (the tool) He used a micrometer to measure the thickness of the circuit board.
The micrometer is a precise measuring tool used in laboratories to accurately determine the thickness or diameter of small objects.
You could use a simple ruler, or a micrometer for greater accuracy.
A Mitutoy micrometer is a name brand microwave that has micrometer waves. Micrometers microwaves are claimed to be able to cook foods more evenly then traditional microwaves.
I've used them for many years and never heard of another name.
Calibrating an inside micrometer is more difficult because it requires access to the inside diameter of a cylinder or hole, which may not be easily achievable compared to the outer surface where an outside micrometer is used. Additionally, inside micrometers are more sensitive to temperature changes and require specialized procedures for accurate calibration.
A "depth gauge micrometer" is used by engineers. A depth gauge micrometer is a precision instrument used to measure various depths of different items.
