CL-3000 Series Confocal Displacement Sensor Brochure

This document describes the Keyence CL-3000 Series confocal displacement sensor, which enables high-accuracy, non-contact thickness measurement for inline inspection. It highlights the sensor's athermal design, optical-axis alignment function, and dedicated jig that eliminate errors from temperature changes, misalignment, and target vibration, solving issues common to conventional methods like beta-ray gauges and contact micrometers.
