Confocal Displacement Sensor

High-precision Measurement on Any Material or Surface.

Ultra-compact coaxial laser displacement sensors for any application in any location.

High-precision measurement on all targets, with simple sensor head installation and program settings.

CL-3000 Series ultra-compact coaxial laser displacement sensors address manufacturing challenges such as improving quality, preventing the shipment of defective parts and increasing production.

In the new multi-color confocal method displacement sensors, the light sources and other parts are all mounted in the optical unit.
Since the lens is the only part inside the head, it is not impacted by heat, electrical noise or other error-producing sources not listed in the specifications.

These are high accuracy displacement sensors that you can truly rely on in manufacturing environments.
