Superior measuring Ability Provides Excellent Performance For Any Measurement Application
A translucent object causes a diffuse reflection beneath the
surface when the laser beam penetrates inside the object and the
received-light wave pattern gently broadens. The RPD algorithm is
able to detect the Real Peak by canceling the impact of the
broadened wave patterns.
*RPD=Real Peak Detect
Optimizes the laser intensity by sensing and adjusting to the reflected light for each layer of a transparent object. High accuracy is accomplished because the measurement is not affected by each layer's reflectivity.
More stable high-definition measurement is attained by combining
two wave form patterns of reflected light from the target. One wave
form is a result of the highly reflective surface while the other
is a result of light reflected from beneath the surface.
*Center and Peak Composition
A wide-area spot that is 2.3 times wider than conventional
A wide-area spot makes it possible to stably measure by averaging the diffuse reflection from the projections and depressions on a coarse target's surface.
*Compared to the LK-G37 and LK-H057.
Extremely small spot Ø25 μm
Extremely small spot, minimum Ø25 μm, detects minute targets with complete accuracy. It is also suitable for profiling.
KEYENCE has developed a sensor head that is dedicated to specular reflection and ensures consistent accuracy with the sensor head positioned for specular reflection. KEYENCE has designed the light-receiving lens optical system specifically for this, in order to significantly improve the linearity. Furthermore, KEYENCE fulfills ±0.02% of F.S by testing the linearity adjustment in manufacturing with sensor heads positioned for specular reflection.
The LK-G5000 Series is equipped with a function to directly measure the speed (m/s) and acceleration (m/s2) of targets. Just select the type of measurement: "displacement", "speed", or "acceleration". Since the differential processing circuit is inside the controller, it is possible to calculate measurements that were previously calculated externally. It is suitable for lightweight, easily deformed, and high-temperature targets which are difficult to measure with a contact sensor.
