Base

•tThe motor-driven spindle moves up/down and stops
when the contact point touches the workpiece. Then the
maximum, minimum values, and runout value are measured
under a constant force.
•tHigh resolution of 0.01μm, and wide measuring range of 50mm.
•tMeasuring system VL-50-B, integrated display type, and VL50S-B, a separate display type, are available.
•tThe measuring table supplied with VL-50-B is ceramic,
corrosion-free for easier maintenance and storage.
•tThe spindle is made of low thermal expansion material.

•tThe Litematic is designed for measuring easily-deformed
workpieces and high-precision parts, with extra-low
measuring force of 0.01N.
•t0.15N and 1N types are capable of measuring at a certain
measuring force by using a Litematic feature, while the 0.01N
type is suitable for measuring delicate workpieces.

Optional Stand for VL-50S-B

This system uses a low-power invisible laser beam (780nm) which
corresponds to a CLASS 1 (invisible radiation) of IEC60825-1 for
measurement. The CLASS 1 laser warning label as shown below is
attached to the main unit.
