Confocal-chromatic principle: Non-contact displacement sensors
The confocalDT confocal-chromatic measurement system consists of a controller with a LED light source and a sensor. The sensor is connected to the controller via fiber optics up to a distance of up to 50 m. The focal distance differs due to the aberration of the chromatic optics of the sensor.
In the controller, a distance is assigned to each long wave. The light reflected from the measuring surface is transferred to the optics of the receiver, where the spectral intensity of the diffused light is evaluated. This unique measurement method allows you to measure displacement and distance with the utmost precision. It is possible to measure both scattering and mirrored surfaces. By using one sensor, you can perform one-sided measurement of the thickness of transparent materials or measure the space between many transparent layers with the simultaneous measurement of the distance.
