A micrometer is a useful instrument used by engineers and metrologists in almost all industries for very precise and accurate measurements. They are extensively used for essential metrological ...

A couple of years ago we published a look at precision measurement tools, in particular vernier calipers and micrometer screw gauges. It featured a look at how they work and how they’re used, and a ...

The new micrometer uses an advanced laser displacement interferometer, which relies on light to measure the thickness of objects held between two metal contacts. With the new system, researchers can ...

Hackaday editors Mike Szczys and Elliot Williams fan through a fantastic week of hacking. Most laser cutters try to go bigger, but there’s a minuscule one that shows off a raft of exotic components ...

Calibration is the process of adjusting and verifying that an instrument, for example, an optical microscope, is taking measurements accurately by comparing them to a known measurement standard or ...
