The laser scan micrometer, such as the Mitutoyo, Keyence, or Xactum brands are amazing precision measurement tools that are used in many manufacturing industries; read on…
Who uses laser scan micrometers?
Aerospace, automotive, mold making, and medical companies are just a few of the end users of these extremely versatile and useful gages. Production companies of all types use them to monitor exact measurements live, in an assembly line.
How a laser scan micrometer works
A laser beam is directed at a mirror, which is rotating a high speed and is synchronized by clock pulses. The reflected beam of light is aimed directly at the workpiece, and when the light is obstructed the output voltage of the photoelectric element varies.
Once the receiving photoelectric cell registers the light, it measures the timed pulses generated by the beam obstruction. This determines the workpiece dimension.
The amazing thing is that this can be done while the workpiece is moving or vibrating. Try that with a precision micrometer or dial indicator!
For this reason, the laser scan micrometer is extremely useful in production lines, manufacturing cells, the precision measurement of delicate items such as contact lenses, and parts that are high temperature.

An authoritative book, “The Metrology Handbook, Second Edition” provides a foundation for understanding basic metrology and calibration principles and practices.
Benefits of the laser scan micrometer
These tools can be used as stand alone micrometers, or applied in an almost any imaginable set-up, such as a conveyor belt or manufacturing cell. By combining them with integrated software, external display units and operator panels, they can be the center of dedicated laser machining and control system.
