Confocal sensors for high precision distance, roughness & thickness measurements

confocalDT IFS2407 sensors are designed for high precision measurement of distance, roughness and thickness. These confocal chromatic sensors offer a high numerical aperture, a small light spot diameter and tolerate large measurement angles, which means that the sensors can also be used for roughness measurements. In addition, the sensors impress with nanometer accuracy.
