Laser Scan Micrometer
Non-contact, high-speed, high-precision measurement

SERIES 544 Laser Scan Micrometer
LSM-902/6900

Optional Accessories

•tNarrow range accuracy of ±(0.3+0.1 D)μm
for high precision measurement.
•tUltra-high repeatability of ±0.05μm.
•tThe system consists of a measuring unit
(LSM-902) and a display unit (LSM-6900).

•tNon-contact laser-based measuring system,
mainly for outside diameter measurement.
Suitable for delicate or moving workpieces.
•tAccuracy of ±0.5μm in the ø0.1 - ø25mm
range can be achieved. It is highly suitable
suited for pin gage measurement.

*1: Determined by the value of ±2 ( : standard deviation)
when measuring ø25mm at the interval of 1.28 sec. (average
1024 times).
*2: At the center of the measuring range.
*3: An error due to variation in workpiece position either in the
optical axis direction or in the scanning direction.
*4: The area given by [optical axis direction]×[scanning direction]
*5: D=Difference in diameter between the master gage and
workpiece (Unit: mm)

Laser safety
Mitutoyo Laser Scan Micrometers use a low-power visible
laser for measurement. The laser is a CLASS 2 EN/IEC608251 (2007) device. Warning and explanation labels, as shown
right, are attached to the Laser Scan Micrometers as is
appropriate.

* Measuring unit dual connection, extra-fine line measurement,
and some of the communication commands are not available.
