Outline and Features of LS-7000 Series
The LS-7000 Series is a high-speed, high-accuracy digital micrometer used for the dimen-
sional measurement of objects without coming into contact with the objects. It is such a
versatile model that it has a wide range of applications including in-line measurement and
offline measurement.
■ Special Features
High-speed Sampling of 2400 Times per Second
Ensures high-speed sampling that is twice as fast as the sampling speed of conven-
tional models. The continuous measurement of extruded products and the in-line
measurement of moving workpieces are possible.
Repeat Accuracy of
±0.15
μ
m
Incorporates the latest optical system, thus ensuring excellent repeat accuracy that is
twice as high as the accuracy of conventional models, thus supporting the manufacture
of high-precision products.
Connecting Two Measuring Heads for two-channel Simultaneous Measurement
Two measuring heads can be used in combination for the simultaneous measurement
of two targets.
Stable Detection of Transparent Objects with Threshold Change
The threshold change function supported by the DE processor makes it possible to
detect transparent objects stably.
■ Principle of Measurement
The high-intensity GaN green LED radiates light, which will be changed into uniform
parallel light through the special diffusion unit and collimator lens and emitted to the
target in the measuring range. Then the shadow image of the target will appear on the
HL-CCD (high-speed linear CCD) through the telecentric optical system. The output
incident signal of the HL-CCD will be processed by the DE (digital edge-detection)
processor in the controller and CPU. As a result, the dimensions of the target will be
displayed and output.
